Sunshine laws are regulations requiring openness in government or business. Sunshine laws make meetings, records, votes, deliberations and other official actions available for public observation, participation and/or inspection. Sunshine laws also require government meetings to be held with sufficient advance notice and at times and places that are convenient and accessible to the public, with exceptions for emergency meetings. As a citizen, you have the right to see these records to know if your government is doing a good job.
On the federal level, the law guaranteeing these rights is the Freedom of Information Act.
