The group wanted access to records of an advisory group that reviewed Dechaine’s case.
Dechaine is serving a life sentence for the murder and rape of a 12-year-old girl in Bowdoin twenty years ago.
In 2002 author James Moore published a book concluding that Dechaine is innocent, and that investigators and prosecutors had acted improperly.
A lower court ruled against Moore’s findings, and in a 3-2 ruling Tuesday, Maine Supreme Court backed the lower court’s ruling.
The high court decided that three lawyers who conducted an independent investigation into the case were acting as private citizens, so they don’t have to share their documents under Maine’s freedom of access law.
