The new rules have come about as a result of the case of a 17-year-old Turkish youth that was wrongly convicted.
He took his case to the European Court of Human Rights that ruled that he had not received a fair trial.
All EU countries are obliged to take account of the ruling and if necessary adapt their rules and procedures.
Those without the means to pay for a solicitor will be entitled to legal aid. It is expected that each year around 30 million Euro extra will be spent on legal aid as a result of the ruling.
The new procedures will come into force from 1 October.
