The UN human rights chief today criticised Nepal's efforts to impeach the country's first female chief justice. Zeid Ra'ad Al Hussein said the move appeared to be aimed at undermining judicial independence. <br/><br/>Nepal's government filed a motion to impeach Sushila Karki after the two main parties in the coalition accused her of interference following a Supreme Court ruling last month overturning Kathmandu's choice for chief of police.<br/>Zeid urged the Nepal authorities to respect the independence of the judiciary and to withdraw impeachment motion. <br/><br/>The impeachment motion was filed days after the court revoked the government's appointment of Jaya Bahadur Chand as police chief, ruling that the government had violated existing processes and regulations.<br/><br/>Karki's supporters say she has taken a strong stance against corruption during her year-long tenure as head of the<br/>supreme court.
