The Indonesian attorney-general is to ask doctors to re-examine former President Suharto to see whether he is fit to stand trial.
Mr Suharto, 84, has been suffering from ill health since his forced resignation in 1998 after 32 years in power.
He was indicted for alleged corruption, but in 2000 a court deemed him unfit to stand trial due to a series of strokes.
On Sunday he made a rare public appearance at a wedding, prompting speculation his health had improved.
Opposition figures and human rights groups have persistently accused the general of corruption and human rights abuses during his decades in power.

The attorney-general said a team of 20 would be asked to re-examine Mr Suharto.
"Doctors said he suffered permanent [brain] damage, but we need to reconfirm that," said Abdul Rahman Saleh.
He told reporters he might consider unspecified other options if doctors concluded the former president was not well enough to face any proceedings.
There has been no indication as to what - if any - charges the former president might face.
In 2000, judges dismissed a US$600m corruption case on the grounds of ill health. http://news.bbc.co.uk/2/hi/asia-pacific/4939482.stm
