The U.N. rights chief has welcomed Pakistan's announcement to reinstate Chief Justice Iftikhar Mohammed Chaudhry and other judges, but says the country needs to do more to guarantee basic rights.

U.N. High Commissioner for Human Rights Navi Pillay says reinstating all 60 judges previously fired is an important step in restoring the rule of law.

Pillay said in a statement Tuesday the government should release all campaigners arrested during recent protests.

The government said Monday that Chaudhry would be sworn back in March 21.

Pillay says Pakistan has to implement international rights law, including an anti-torture treaty and rules on basic political and civil rights.
