Greece is threatening to sue the EU institutions and seek a court injunction to block the country's expulsion from the euro and stop a suffocation of the banking system.
"The Greek government will make use of all our legal rights," said Yanis Varoufakis, the finance minister.
"We are taking advice and will certainly consider an injunction at the European Court of Justice," he told The Daily Telegraph.
"The EU treaties make no provision for euro exit and we refuse to accept it. Our membership is not negotiable."
Greek officials said they were seriously considering suing the European Central Bank for freezing emergency liquidity for the Greek banks at 89bn.
It turned down a request from Athens for a 6bn increase to keep pace with deposit flight.
This effectively pulled the plug on the Greek banking system, in what the ruling Syriza party claimed was a breach of the ECB's legal duty to maintain financial stability. "How can they justify setting off a run on the Greek banking system?" asked one official.
