BBC: Millionaire Stuart Wheeler has won his battle to force a High Court review into whether the government should hold a referendum on the EU's Lisbon treaty.
Prime Minister Gordon Brown has ruled out a public vote on the treaty, saying it does not alter the UK constitution.
But Mr Wheeler said a vote was promised on the EU constitution and says the Lisbon treaty is virtually identical.
The hearing will be on 9 and 10 June. The Foreign Office said they were "confident" of their case.
In March MPs voted by 346 votes to 206 to approve the EU (Amendment) Bill, after topic-by-topic debates over six weeks.
The Bill - which is now in the Lords - will ratify the Lisbon Treaty, which was drawn up to replace the EU constitution after that was rejected by French and Dutch voters in 2005. Court Challenge to EU Referendum >>> | May 2, 2008
