The report was handed over to the Supreme Court in a sealed envelope on January 16.
The report into Justice BH Loya's death says there was no foul play in the judge's death, sources in the Maharashtra home ministry have told the Zee Group.
Judge Loya had died of cardiac arrest in Nagpur on December 1, 2014, when he had gone to attend the wedding of a colleague's daughter. At that time was hearing the Sohrabuddin Sheikh fake encounter case, in which Bharatiya Janata Party (BJP) president Amit Shah is an accused.
The judge who replaced judge Loya, had ruled that there was no evidence against the BJP chief to be put on trial.
Foul play in the judge's death, after speaking to his family, was first alleged by a magazine.
