Members of Parliament and locals in the restive Rwenzori region are furious.
President Museveni has halted the Defense Committee from investigating on the circumstances that triggered the military assault on Rwenzururu Kingdom’s Buhikira palace last month.
Thus ongoing investigation by the parliamentary committee on defence and Internal Affairs may have hit a snag.
Committee chairperson and Mityana Woman MP, Judith Nabakooba, said the head of state’s office insists this is because the issue is before court.
“We were advised that it is sub judice,” Ms Nabakooba said.
At least 116 people have been confirmed to have died during the raid, which also reportedly left an unknown number of both adults and children either injured or missing.
Museveni is said to have wrote to Speaker of parliament Rebecca Kadaga through the Attorney General ordering her to halt the probe.
The president says the committee investigations contravene the subjudice rule and its findings could bias judges hearing the cases against King Mumbere and other suspects in connection with the violence in Kasese.
Parliament’s Director of Communication and Public Affairs Chris Obore says they are yet to receive the president’s letter.
Efforts to have access King Mumbere have been futile due to the ongoing court process, where he was charged with terrorism, murder and robbery, among others.

Mr Museveni has not made any public comments about the killings or torching of the palace.
Mr Museveni has come under criticism for his role in ordering the attacks. MPs from the affected areas say they are preparing to file a suit in the International Criminal Court calling for the prosecution of senior military and other officers suspected to have committed crimes against humanity during the military assault.
Mr Museveni is only quoted as having told army high command members on December 7 that King Mumbere refused orders to disarm, disband and surrender the royal guards, thus justifying the raid on his palace.
