Kennedy cousin Michael Skakel will be back in a Connecticut courtroom on Wednesday as state prosecutors petition for the reinstatement of his 2002 conviction for the 1975 murder of Martha Moxley, Skakel’s lawyer confirms to PEOPLE.

Attorney Stephen Seeger tells PEOPLE it could take several months for seven Supreme Court justices to render a decision following Wednesday’s appeal hearing in Hartford.

Skakel, 55, was released in 2013 after a judge granted him a new trial in Moxley’s killing.

Skakel is a nephew of Robert F. Kennedy’s widow, Ethel, and was Moxley’s neighbor in Greenwich, Connecticut, when the 15-year-old girl was bludgeoned to death with the shaft of a broken golf club.

A judge ruled two years ago that Skakel’s trial lawyer failed to adequately represent him during the 2002 trial, which resulted in a 20 years to life prison sentence.

Skakel was freed on November 21, 2013 after posting $1.2 million bond. He is required to wear a GPS monitoring bracelet as a condition of his release.

Prosecutor Susann Gill did not return calls seeking comment Tuesday.

Skakel s cousin, Robert F. Kennedy, Jr., has written a book about the case called Media Lynching: The Persecution of Michael Skakel. The book is due to be released in April.
