The issue has to do with alleged misdeeds in helping elect her brother to a ward assembly. Apparently, Mynamar has a malfeasance standard:
hluttaw representatives can be recalled for high treason, breaching the constitution, misbehavior failing to meet the criteria for a hluttaw representative and inefficient discharge of duties.
Petitioners need at least 1 percent of the “original” voters in the electorate to submit a complaint to the Union Election Commission, which then investigates the allegation. However, to allow a recall has not been approved.
