KUALA LUMPUR: Sipitang MP Yamani Hafez Musa could lose his eligibility to become an MP if he does not turn up in parliament to be sworn in within a stipulated time frame. The former Sabah Umno Youth chief who is also the son of former Sabah chief minister Tan Sri Musa Aman has yet to take his oath of office since parliament kicked off on July 16 this year and it is reported that his whereabouts are unknown. Speaker of the August house Datuk Mohd Ariff Yusof said that Yamani, who won the seat in GE14, should be aware of his position in line with the federal constitution. "If he exceeds the threshold (to be sworn in) then the law kicks in. There's nothing I can do, there's nothing you can do. It's the law," said Ariff. "He can read the Federal Constitution. He should know his position," he said. Under article 59 of the federal constitution, if a member has not taken his seat within six months from the date on which the House first sits after his election or such further time as the house may allow, his seat shall become vacant. It was reported that Yamani went missing sometime after May 9, the night Pakatan Harapan wrested power from the Barisan Nasional Party.
