During his annual visit to the NAB Rawalpindi Regional Headquarters, Mr Chaudhry was told that the Sharif brothers had again taken a fresh stay order from the Lahore High Court.
A source told Dawn that the Sharif brothers had taken advantage of stay orders since their cases were reopened in 2007 when the Supreme Court allowed Nawaz Sharif to return to Pakistan from exile.
Three corruption references and at least six inquiries have been pending with NAB and accountability courts against the Sharif brothers and other members of their family.
The source said the NAB Rawalpindi had entertained more than 90 per cent of major corruption cases.
The NAB chief was informed that out of more than two dozen major corruption cases, only two or three were pending.
