Supreme Court Justice Devendra Gopal Shrestha, one of the seven justices in the bench formed to hear on the Nepal Police Inspector General appointment row, has been barred to seat in the court proceeding owing to his family relation with DIG Nawaraj Silwal.

Supreme Court on Thursday had formed a seven-member bench comprising of justices Devendra Gopal Shrestha, Cholendra Shamsher JBR, Jagadish Sharma Poudel, Dip Kumar Karki, Kedar Prasad Chalise, Sapana Pradhan Malla and Tej Bahadur KC to look into the case.

DIG Silwal had filed a case at the apex court after government appointed Jaya Bahadur Chand as IG. SC quashed government's appointment and directed it to make the appointed based on merit and seniority.

Government then appointed Prakash Aryal as new police chief arguing he had received highest marks on the score of performance evaluation. Silwal against knocked SC's door against the appointment.

When Silwal was arrested on charges of forging performance report, SC ordered the government to stop action against him.

A Nepali Congress and CPN (Maoist Center) coalition filed an impeachment motion against Chief Justice Sushila Karki accusing her of interfering in the jurisdiction of executive and failing to issue verdicts without being prejudiced. The motion has since been stayed by an interim order by Supreme Court.
