The state Court of Appeals on Tuesday rejected a motion by Staten Island District Attorney Daniel Donovan Jr. to file under seal his brief in a political case involving the Working Families Party and a 2009 City Council election on Staten Island.

Donovan, who sought to be relieved from the case for reasons he has never publicly disclosed, had asked the high court for permission to file his brief under seal, and also asked to serve his adversaries a redacted version. In a terse order Tuesday, the court denied the motion.
