Me. Rev. Stat. Ann. tit. 15 § 3307(2) (1997): Juvenile hearings are open to the public if the crime would constitute murder or certain felonies if committed by an adult.

Me. Rev. Stat. Ann. tit. 15 § 3308 (1997): If the proceeding is open to the public, the records are open to the public. The petition, the record of the hearing and the order of adjudication are open to inspection by the victim regardless of whether the hearing is open to the general public. Records of proceedings not open to the public can be inspected by persons with a legitimate interest in the proceedings, if the court consents. In those cases, the names of the juvenile, his parents, guardian, legal custodian, his attorney or any other parties shall be excluded. In addition, a person adjudicated to have committed a juvenile crime may petition the court to seal all records if at least three years have passed since the time of adjudication, the person has not been convicted of another crime, and no other criminal charges are pending. The court may grant the petition unless "it finds that the general public’s right to information substantially outweighs the juvenile’s interest in privacy."

Access to documents: A Maine Superior Court held that when a newspaper legally obtains documents, even if the reporter should not have been allowed to view them, it cannot be enjoined from publishing the information. State v. Yard, No. CV-83-897 (Me. Super. Ct., Aug. 26, 1983).
