Wang said that further investigation was needed to clarify the matter.
In response, the Presidential Office yesterday issued a statement saying it respected the Ministry of Audit's decision to request a judicial investigation regarding the expenditures.
The statement said that the Presidential Office had followed past practices in filing reimbursement expenses, using receipts that do not specify the details of the expenses.
It said that such practices had been in place since the 1950s, because nearly half of special allowance expenditures were used for confidential purposes.
The Presidential Office said that similar methods of filing had been used in 2004, and the Ministry of Audit had not found fault with the method then, the statement said.
However, in light of the dissatisfaction of the auditors regarding the expense-filing method, the Presidential Office said that it would review the method and make it more transparent in the future.
