Victorian Premier Ted Baillieu has blamed legal aid funding shortfalls on the Federal Government.
Two Supreme Court judges have suspended serious criminal trials in the last week, amid concerns the accused would not receive a fair trial.
The Mental Health Legal Centre in Melbourne also claims vulnerable clients are being affected by funding shortfalls.
Mr Baillieu says funding for legal aid is a joint arrangement and the shortfall is the Commonwealth's fault.
"We've already increased funding for Legal Aid in the last budget by more than $20 million," he said.
"It's the Federal Government who haven't been adding to their component of it.
"We're disappointed about that. The Attorney-General's made that point a number of times."
