Pangu Pati leader and Bulolo MP Sam Basil has passed on the Opposition leadership to Kandep MP Don Pomb Polye.
The handover of the leadership was done accordingly and followed every process.
Basil welcomes Polye back and handed over the position in front of his other Opposition members this afternoon in Port Moresby.
Polye had stood down from the position after the National Court set aside his 2012 election over disputed ballot boxes.
After a successful election petition by runner-up, Alfred Manase, the court on May 2, ruled that five ballot boxes in Polye's Kandep electorate were not properly counted by the Electoral Commission.
After the decision Polye relinquish the leadership to Basil.
However, Polye has been reinstated after the Supreme Court on Tuesday May 24 stayed that earlier decision removing him from Parliament.
The Court decision now means that Polye will remain as a Member for Parliament while a Supreme Court bench will hear his application.
