Pakistan's Supreme Court on Thursday firmly told embattled Premier Yousuf Raza Gilani that he had no option but to write to Swiss authorities to revive graft cases against President Asif Ali Zardari as no one was above the law.

Hearing Gilani's appeal against an apex court order summoning him on February 13 for framing contempt charges over his failure to act on its directive to reopen corruption cases against Zardari, an eight-judge bench headed by Chief Justice Iftikhar Chaudhry said the Prime Minister should have taken the initiative.
