The newly elected Mr Lee can go unrestrained if there is no check-and-balance on the expanding power of the President, an ousted Kuomintang Central Committee member warned yesterday.
Professor Andy Sun urged the National Assembly to amend the constitution to stipulate methods to monitor presidential powers.
The dissident also called on Mr Lee to give the decision-making power back to the island's legislature.
'He has to deeply understand that according to the present constitution, the power and responsibility of a president has no direct relationship with the way the president is elected,' said Professor Sun, now a member of the New Party, a splinter group of the KMT.
'The real centre of decision-making should not be the Presidential Office, but the Legislative Yuan. Only if he genuinely respects the constitution, can we embark on the true road of democracy,' he said.
Professor Sun was dismissed from his Central Committee position in May last year after he advocated the KMT candidate for the presidential election should be directly elected by all party members.
He had also called for the setting up of a system to supervise the management of the party's properties which are a mystery to most KMT members.
