Victorian Attorney-General Robert Clark has thrown his support behind Legal Aid and its decision to restrict funding for criminal trials in the state.

Victoria Legal Aid recorded a $3 million deficit last financial year.

It is now restricted its funding for criminal trials to a barrister and an instructing solicitor for two half-days.

due to the lack of funding for a full-time solicitor from Victoria Legal Aid.

They say the cuts to Victoria Legal Aid mean defendants will not get a fair trial.

The Law Institute of Victoria has also slammed the decision and says Legal Aid desperately needs a $10 million funding injection.

But Mr Clark has told 7.30 Victoria, the Government does not agree.

"Victoria Legal Aid needs to spend taxpayers' dollars wisely and effectively to ensure that as many people as possible can be assisted with the money it makes available," he said.

"It's fully entitled to explore opportunities for change and improvement right across the legal system.

"Legislative and non-legislative reforms are being pursed by the courts, by legal aid, by the DPP."

Mr Clark disagrees with two of the state's trials being put on hold and questions the need for two lawyers in the cases.

"The Victorian Government is fully supportive of their [Legal Aid's] efforts to spend money wisely and to ask why two lawyers are needed in every trial in Victoria, when in other states, Western Australia and South Australia, Tasmania, the Northern Territory that's not the case," he said.
