Offentlighets- och sekretesslagen (2009:400)

This Swedish law governs the balance between the public's right to access official documents and the necessity of maintaining confidentiality. It ensures transparency in government operations while protecting sensitive information, such as national security, personal privacy, and commercial secrets. All Swedish public authorities and individuals interacting with them are affected. The law dictates how much information citizens can request from the state and defines the specific legal grounds under which information must remain secret.
