The woman who led the legal battle against the British government's ability to push forward with Brexit has reacted to a high court decision in her favour.

Britain's High Court ruled on Thursday that the prime minister cannot trigger the UK's exit from the European Union without approval from Parliament

Financial entrepreneur Gina Miller, who supported the campaign to stay in the European Union, brought the case.

She argued that leaving the EU would deny her fundamental rights, such as the right to free movement and freedom of services across Europe.

The case is considered the most important constitutional matter in a generation.

It centres on whether Prime Minister Theresa May can start negotiating Britain's exit from the EU without a vote in the House of Commons.

At the core of the matter is the balance of power between Parliament and the government.

Regardless of the victor, the case will likely be immediately appealed to the Supreme Court.

May has said she will invoke Article 50 of the EU treaty - triggering two years of official exit talks - by March 31.

"A few words: the result today is about all of us. It's not about me or my team. It's about our United Kingdom and all our futures. It's not about how anyone voted. Every one of us voted for the best country and the best future. This case was about process, not politics. My dedicated team at Mishcon (legal team), and counsel and I are absolutely delighted that we've been able to be part of this debate, and to bring some sobriety as we go forwards. The judgement, I hope, when it's read by the government - and they contemplate the full judgement - that they will make the wise decision of not appealing, but pressing forwards and having a proper debate in our sovereign parliament, our mother of parliaments that we are so admired for around the world. Thank you."

There was a mixed reception on the streets of London on Friday a day after the high court ruled that that the British government needs Parliament's approval before formally triggering talks on leaving the EU.

Many of those who voted to 'Remain' welcomed the development, but others saw it as an attempt to block the Brexit process.

Thursday's High Court ruling that the government needs Parliament's approval before invoking Article 50 of the EU treaty, which formally begins a two-year countdown to Britain's exit.

The government is appealing against the ruling at the Supreme Court with a hearing expected next month.

If the country's highest court rules against the government, Parliament will become directly involved in discussions over how the Brexit process begins.

Because this is a democracy and you have different organs of government and the whole process was very hastily set up, very shabbily organised, and people were lied to, so they voted for something they didn't mean to vote for. So now, you have to have another organ of government...checks and balances. You can hear I'm American. We need some checks and balances over there too."

They're showing us it's undemocratic."

Britain's government must get parliamentary approval before starting the process of leaving the European Union, the Supreme Court ruled on Tuesday.

The decision potentially delays Prime Minister Theresa May's plans to trigger exit negotiations by the end of March.

In a major blow for Britain's government, the High Court said the prime minister can't trigger the UK's exit from the European Union without approval from Parliament.

The government is likely to appeal Thursday's ruling to the Supreme Court.

Claimants argue that leaving he EU will remove rights, including free movement within the bloc, and say that cannot be done without Parliament's approval.

Gina Miller, financial entrepreneur and the lead claimant in the High Court case, said the proper place for a debate on leaving the EU is in a sovereign Parliament.

Prime Minister Theresa May says the June 23 referendum on EU membership gave her a mandate to take Britain out of the 28-nation bloc.

British Prime Minister Boris Johnson says he strongly disagrees with the Supreme Court ruling that Parliament's suspension was illegal.

He says the government will respect the decision but indicated he could try to suspend it again.

Johnson said in New York Tuesday that "I strongly disagree with this decision of the Supreme Court" and "I don't think this was the right decision."

He added: "It's perfectly usual to have a Queen's Speech, that's what we want to do."

The Queen's Speech outlines the government's plan for the coming session of Parliament.

Johnson's office meanwhile said he will not resign.

Downing St. said Johnson will fly back from a U.N. General Assembly in New York overnight, earlier than planned.

That will bring him back to London by the time Parliament resumes on Wednesday.

This comes as UK House of Commons Speaker John Bercow welcomed the Supreme Court's ruling that the suspension of Parliament was illegal and said that members are set to resume their work on Wednesday morning.

He said citizens are "entitled" to have Parliament perform its core constitutional duties.

Whitle an anti-government protester outside the court welcomed the ruling and said MP's should go back to Parliament as soon as possible.

"We are in a national crisis right now, and we leave the European Union in just over a month so we need to get back in there and start talking about it because if we don't then we're gonna have some big problems," said Jacob Archbold.

Pro-Brexit demonstrators, meanwhile, chanted slogans of support for Johnson.

But Brexit supporter Michael McFadden also said that Johnson and the Conservatives had "destroyed themselves" and accused former Prime Minister Theresa May of making Brexit backers "look a bunch of fools and we are not a bunch of fools."

The landmark decision immediately prompted calls for Johnson to quit.

In a major blow to Prime Minister Boris Johnson, Britain's highest court ruled Tuesday that his decision to suspend Parliament for five weeks in the crucial countdown to the country's Brexit deadline was illegal.

The unanimous, strongly worded Supreme Court judgment declared the order to suspend Parliament "void and of no effect."

The court found that Johnson acted to limit debate on Britain's impending departure from the European Union in violation of Parliament's constitutional role.

House of Commons Speaker John Bercow welcomed the historic verdict and said Parliament would resume its business Wednesday morning.

There will not be a Prime Minister Questions session in Parliament on Wednesday because Johnson is in New York for the U.N. General Assembly.

An anti-government protester outside the court welcomed the ruling and said MP's should go back to Parliament as soon as possible.

Scotland's First Minister Nicola Sturgeon on Tuesday said she was "disappointed" after Britain's Supreme Court ruled that Scotland, Wales and Northern Ireland will not need to be consulted before starting the process of leaving the European Union.

Speaking in Edinburgh, Sturgeon said, despite the ruling, that it was the UK government's "political obligation...to listen to the devolved administrations."

She also welcomed the news that MPs will vote on the triggering of Article 50.

1. SOUNDBITE (English) Nicola Sturgeon, Scotland's First Minister:

"Well I welcome the Supreme Court ruling that an act of parliament is required in the House of Commons before the triggering of Article 50. I think that ruling is an indictment of a UK government that thought it could press ahead without any reference to Parliament whatsoever. So it's now vital that parliament gets the chance to debate and decide upon, not just the triggering of Article 50 but I think the terms of the negotiating position as well, and SNP MPs will seek to work with others to stop a hard Brexit in its tracks."

++BLACK FRAMES++

2. SOUNDBITE (English) Nicola Sturgeon, Scotland's First Minister:

"Scotland voted against Brexit and therefore I think it is inconceivable that SNP MPs would vote for the triggering of Article 50. But I think it's important that the House of Commons and parliament is involved not just in that narrow question whether to trigger Article 50 but also the terms of the negotiations. The Prime Minister set it last week, a path towards the hardest of hard Brexits. I don't believe there's a majority for that in the House of Commons and I certainly don't believe there's majority for that across the country so this is an opportunity for the House of Commons to assert itself and to have a say not just on the narrow question but on the broader terms of negotiations as well."

++BLACK FRAMES++

3. SOUNDBITE (English) Nicola Sturgeon, Scotland's First Minister:

"I am disappointed at the Supreme Court ruling about the rule of the devolved administrations and I think it raises a really important question for the UK government after the Smith Commission following the independence referendum. They were at great pains to see that the Sewel Convention was to be embedded in legislation and therefore that it was taking on a more important role in the devolved arrangements. Now, what was the point of embedding it in legislation if it's not legally enforceable? I think that commitment from the UK government today has been shown to be not worth the paper it's written on. That said the court is very clear, that Brexit will touch upon the devolved competencies of the devolved administrations and recognises the importance of Sewel as a political convention. So I think that there's still a political obligation for the UK government to listen to the devolved administrations, we will certainly bring forward a legislative consent motion because I think it's important that the Scottish Parliament has the right to vote on whether or not it is prepared to consent the triggering or not of Article 50."

++BLACK FRAMES++

4. SOUNDBITE (English) Nicola Sturgeon, Scotland's First Minister:

"But there's nothing in the Supreme Court's ruling that's says that Sewel Convention should be ignored completely as a political convention. Clearly Brexit impinges upon the devolved competencies, not just of the Scottish parliament but the Welsh Assembly and the Northern Irish Assembly, as well. And I think it's a matter of democratic principle that the Scottish parliament on such a big fundamental issue with so many implications for the devolved settlements should have a say on whether or not it consents to the triggering of Article 50. So we will bring forward a motion that allows the Scottish Parliament to do that and I will then hope that the UK government would pay attention to it."

++BLACK FRAMES++

5. SOUNDBITE (English) Nicola Sturgeon, Scotland's First Minister:

"I have made very clear that that option is very very much on the table and as I have said before with every day that passes right now it's becoming clearer that Scotland's voice cannot and is not able to be heard within the UK on this question. That raises big issues. I have set down a path of process of exhausting and exploring all options. I will continue to do that but be in no doubt that I think the decision is looming for Scotland. Are we prepared to allow our future to be dictated by a Westminster government that's gone down a path I think the majority of people in Scotland do not want to go down or are we going to take our futures in our own hands?"

UK Brexit Secretary Stephen Barclay said Thursday that his government will respect the outcome of an expected ruling by Britain's top court on whether Prime Minister Boris Johnson acted unlawfully when he suspended Parliament.

Johnson sent lawmakers home until 14 October, and his opponents claim he did it to prevent them scrutinizing his plan to take Britain out of the EU at the end of next month, with or without a divorce deal.

Speaking during a visit to Madrid, Barclay said the government would "abide" by the Supreme Court's ruling.

The court was hearing final arguments Thursday. Judges were set to hear from a lawyer for the former prime minister, John Major, who is among those challenging the decision by Johnson, one of his successors as Conservative leader.

Opponents have also accused the prime minister of misleading Queen Elizabeth II, whose formal approval was needed to suspend the legislature.

The government says the suspension is routine and not motivated by Brexit, and argues that judges should not interfere in politics.

Opposition leader Jeremy Corbyn has welcomed Tuesday's Supreme Court ruling that UK parliament should be consulted before the government triggers Article 50 to leave the European Union.

The Labour party leader said he would not block the government's plan to invoke Article 50 by the end of March, saying "it doesn't mean we abdicate the field, it means we then hold the government to account".

It doesn't mean we abdicate the field, it means we have to hold the government to account on the issues of trade, the issues of rights and the issues of the long-term direction in which this country wants to go. Because the strange thing about the Prime Minister's speech was this implied threat that if Europe doesn't do what she wants, then she's going to turn us into some Singapore-style economy on the shores of Europe. Well, that is not what people voted for, people voted for leaving the European Union, they didn't vote to vote themselves out of work."

Frankly, there should be a proper statement of what the government intends to do on this. We have been making the point ever since the referendum that parliament must be involved. We must be able to hold the government to account, that's what parliament exists for, to hold them to account to make sure that the negotiations actually are for the benefit of all the people of this country, however they voted in the referendum."

We need to be informed, be able to challenge, be able to overturn if necessary, the objectives and direction in which the government is going on those negotiations. There is also going to be the Great Repeal Bill which will come up presumably during the coming summer. That's going to be an enormous piece of legislation because it is amending 40 years of UK parliamentary legislation, all of which at some point or the other usually refers to European regulations. But we're very clear; we're going to hold them to account. We're going to hold them to account to protect jobs, we're going to hold them to account to make sure British industry does have market access and we're not going to allow ourselves to become some kind of off-shore tax haven.

British Prime Minister Boris Johnson said he strongly disagrees with the Supreme Court ruling that Parliament's suspension was illegal.

He said the government will respect the decision but indicated he could try to suspend it again.

"It's an unusual judgment to come to, in my view. Parliament has used prorogation for many... the prerrogative of prorogation is a very old one and it's not I think been contested before in this way,"Johnson said in New York, where he was attending the U.N. General Assembly.

Johnson did not rule out trying to suspend Parliament again.

"I don't think that the justices remotely excluded the possibility of having a Queen's Speech but what we will certainly do is ensure that Parliament has plenty of time to debate Brexit," Johnson said.

The unanimous, strongly worded Supreme Court judgment on Tuesday declared Johnson's order to suspend Parliament "void and of no effect."

The court found that Johnson acted to limit debate by lawmakers on Britain's impending departure from the European Union in violation of Parliament's constitutional role.

A British constitutional analyst said Tuesday's Supreme Court ruling that UK Prime Minister Boris Johnson illegally suspended parliament was a "serious defeat" for the government and that the decison upheld the "fundamentals" of the constitution.

Professor Robert Hazell of University College of London told said that the unanimous ruling was based on two principles, parliamentary sovereignty and parliamentary accountability.

Members of Parliament will resume proceedings on Wednesday instead of on October 14 - the original prorogation date which was set less than three weeks before Britain's scheduled departure from the European Union.

Hazell said the extra time for debate in the lead-up to Brexit would be "important" so "parliament can scrutinise and hold the government to account".

Johnson's Conservative Party colleague, Sir Alan Duncan, sided with the ruling and said that it was important "to defend the integrity of our courts process and our judicial process".

On the streets of Belfast in Northern Ireland, an area which could be affected by the so-called Irish "backstop" agreement, reaction to the ruling was mixed.

Resident Brian Strong said the decision would hopefully mean parliament would have more time to review the controversial backstop, which acts as an insurance policy for an open Irish border.

The deputy leader of the Irish Republican party, Sinn Fein, has called on British Prime Minister Boris Johnson to resign following a court ruling by the Supreme Court on Tuesday that his decision to suspend Parliament for five weeks in the crucial countdown to the country's Brexit deadline was illegal.

"I believe on the back of this ruling today and all of that mess that dominates the British political landscape for the last two and a half years, Boris Johnson should go. Boris Johnson should resign. Boris Johnson is not in command of his own agenda,"  Michelle O'Neill said.

The unanimous, strongly worded Supreme Court judgment declared the order to suspend Parliament "void and of no effect."

The court found that Johnson acted to limit debate on Britain's impending departure from the European Union in violation of Parliament's constitutional role.

Downing Street said on Tuesday that Johnson, who is in New York to attend a UN summit, will not resign as prime minister in the wake of the ruling.

"It clearly again demonstrates that this British government has lost control of its own agenda. It is a constitutional crisis - we've been saying that for some time - and I believe this is another one of those meltdown moments for this British government. All the while while that mess continues, while that chaos continues, while the Tory party fight internally, what we have here is a situation where the people did not vote for Brexit. There is not one good, positive thing to point to in terms of this Brexit agenda. It's reckless, it's catastrophic for our people and our industries."

"So we are 37 days out from the Brexit deadline, the 'do-or-die' agenda of Boris Johnson. But at the end of the day, the people here need a deal, the agri-food industry needs a deal, the services sector needs a deal, manufacturing needs a deal. So I believe on the back of this ruling today and all of that mess that dominates the British political landscape for the last two and a half years, Boris Johnson should go. Boris Johnson should resign. Boris Johnson is not in command of his own agenda. What I'm interested in is standing up for the interests of people who live here in this island, and what I'm interested in is standing very firm against the reckless Tory-DUP Brexit agenda."

British Prime Minister Boris Johnson says he strongly disagrees with the Supreme Court ruling that Parliament's suspension was illegal.

He says the government will respect the decision but indicated he could try to suspend it again.

Johnson said in New York Tuesday that "I strongly disagree with this decision of the Supreme Court" and "I don't think this was the right decision."

He added: "It's perfectly usual to have a Queen's Speech, that's what we want to do."

The Queen's Speech outlines the government's plan for the coming session of Parliament.

Johnson's office meanwhile said he will not resign.

Downing St. said Johnson will fly back from a U.N. General Assembly in New York overnight, earlier than planned.

That will bring him back to London by the time Parliament resumes on Wednesday.

1. SOUNDBITE (English) Boris Johnson, British Prime Minister:

"I strongly disagree with this decision of the Supreme Court. I have the utmost respect for our judiciary. I don't think this was the right decision. I think that the prerogative of prorogation has been used for centuries without this kind of challenge. It's perfectly usual to have a Queen's Speech, that's what we want to do. But more importantly let's be in no doubt, there are a lot of people who want to frustrate Brexit. There are a lot of people who basically want to stop this country coming out of the EU and we have a Parliament that is unable to be prorogued, unable to...doesn't want to have an election and I think it's time we took things forward."

(Journalist asking off-camera): "You said you won't extend Brexit but how do you avoid doing that now? You've run out of options."

Johnson: "Well on the contrary. As the law currently stands, the UK leaves the EU on October the 31st come what may. But the interesting thing, the exciting thing for us now is to get a good deal and that's what we're working on. And I'll be honest with you, John, it's not made much easier by this kind of stuff in Parliament or in the courts. Obviously getting a deal is not made much easier against this background but we're going to get on and do it."

(Journalist asking off-camera): "Just finally, you say as the law stands we leave on October the 31st. That's not true is it? As the law stands we cannot leave with no deal on October 31st without the permission of Parliament."

Johnson: "As the law stands we leave on October the 31st and I'm very hopeful that we will get a deal and I think what the people of the country want is to see our parliamentarians coming together, working on, in the national interest to get this thing done and that's what we're going to do."
