The Pennsylvania Right to Know Act, also known as the Pennsylvania Sunshine Law, is a series of laws designed to guarantee that the public has access to public records of governmental bodies in Pennsylvania.
The Pennsylvania Sunshine Act legislates the methods by which public meetings are conducted.
Prior to 2008, the Pennsylvania Right to Know Act was widely regarded as one of the worst in the country, partly because the pre-2008 law presumed that government records were not public, unless someone who wanted the record could establish otherwise. A new law passed by the state legislature and signed by Gov. Ed Rendell "flipped the presumption". This new law went into full effect on January 1, 2009 and it states, in sharp distinction to the previous law, that all documents will be presumed to be open to the public unless the agency holding them can prove otherwise
