Suu Kyi, 76, faces nearly a dozen cases against her, including incitement and violation of Covid-19 protocols. She has denied all the allegations so far.
Ms. Suu Kyi and her ruling National League for Democracy party were ousted when the military took power in a February 1 coup, ostensibly due to allegations of electoral irregularities. She has been detained at an undisclosed location in the capital ever since. Her lawyers and supporters consider the charges against her to be politically motivated.
A spokesman for Myanmar’s military government did not respond to calls from Reuters seeking comment. Suu Kyi’s lawyers, who have been issued a gag order in connection with the cases, could not be reached for comment.
