Pakistan's Supreme Court on Friday struck 
down a recently passed law to protect the prime minister from being 
charged with contempt of court and ousted from office, like his 
predecessor, for refusing to reopen an old corruption case against the 
president.
The ruling comes less than a
 week before the deadline set by the court for the current premier, Raja
 Pervaiz Ashraf, to tell the judges whether he will obey their order to 
write a letter to Swiss authorities asking them to reopen the graft 
case.
The government and court 
have been locked in conflict over the issue since the beginning of the 
year, stoking political instability that has distracted from what many 
in the country see as more pressing problems, such as the struggling 
economy and a Taliban insurgency.
The court could repeatedly disqualify prime ministers over the issue, undermining the government and forcing an early national.
Parliament passed the new 
law in early July after former Prime Minister Yousuf Raza Gilani was 
convicted of contempt and forced to step down. The law provided greater 
protection to the prime minister and other senior government officials 
against contempt charges.
The court struck down the 
law because it violated the basic principle of equality among the 
country's citizens, said Zafr Ullah, a lawyer who challenged the law.
The government has refused 
to reopen the corruption case against Zardari, saying he enjoys immunity
 from prosecution while in office. His supporters have accused the court
 of relentlessly pursuing the matter because of bad blood between Chief 
Justice Iftikhar Chaudhry and the president.
The new prime minister, 
Ashraf, has also indicated he has no plans to write the letter to Swiss 
authorities. If the court convicts him of contempt and orders his 
removal from office, the government would be forced to once again seek 
support in parliament to elect a new premier or call early national 
elections.
It's unclear which option 
the government would choose. The ruling Pakistan People's Party has been
 keen on holding elections as scheduled in early 2013 because it could 
then boast being the first civilian government to serve a full five-year
 term in the country's 65-year history. Past governments have been 
toppled by the direct or indirect intervention of the army, often with 
the help if the judiciary.
The case against Zardari 
relates to kickbacks he and his late wife, former Prime Minister Benazir
 Bhutto, allegedly received from Swiss companies when Bhutto was in 
power in the 1990s. They were found guilty in absentia in a Swiss court 
in 2003.
Zardari appealed, but Swiss
 prosecutors dropped the case after the Pakistani parliament passed an 
ordinance giving the president and others immunity from old corruption 
cases that many agreed were politically motivated.
The measure was criticized 
by many in Pakistan, who saw it as an attempt to subvert the law. The 
Supreme Court ruled it unconstitutional in 2009 and ordered the 
government to write to Swiss authorities requesting they reopen the 
case.
A Swiss prosecutor told the
 media last year that Geneva couldn't bring proceedings against Zardari 
because he has immunity as a head of state.
The Supreme Court has also 
said it would respect the president's immunity, but it still wants the 
government to write the letter to the Swiss and is frustrated the 
government has long disobeyed its orders to do so.
The court has ordered the government to declare whether it will write the letter by Aug. 8.
