OLYMPIA — A task force created after Washington lawmakers attempted to exempt themselves from the state’s Public Records Act says the Legislature should be more transparent about its workings. The group, which includes lawmakers and news media representatives, approved several guidelines for how the Legislature should handle the issue of public records at its final meeting Friday. Members agreed that disputes about whether specific records are public should be handled by an independent body, and that privacy protections already in the Public Records Act should cover communications that people have with lawmakers.
