Page "President of the Republic of China" Paragraph 17

As no president of the Executive Yuan ( also known as the Premier ) has ever succeeded to the presidency under these provisions ( or their predecessors, under Article 49 ), it is untested whether, should the office of the premier be vacant as well, whether, pursuant to the Additional Articles, Article 3, the vice president of the Executive Yuan ( vice premier ), who would be acting premier, would act as president.

There is currently no constitutional provision for a succession list beyond the possibility that the vice president of the Executive Yuan might succeed to the presidency.
