Michael Morton says he wants to ensure that prosecutors could be fined or even disbarred for concealing facts in the courtroom.
In an interview Thursday, the 57-year-old said he plans to get new rules enacted in Texas by working with lawmakers and the State Bar of Texas, and using the fame generated by his high-profile case.
Morton was convicted in the 1986 beating death of his wife. But he was freed in October after DNA evidence linked another man to the murder.
A special prosecutor is now investigating allegations that the prosecutor in Morton's case, Ken Anderson, hid evidence. Anderson is now a judge.
