LONDON — The Vienna State Opera on Friday removed all responsibilities from Simona Noja-Nebyla, the managing director of its historic ballet academy. The move came just days after an independent commission said the academy had endangered the well-being of its students.

The academy had given its students “insufficient medical and therapeutic care,” the commission, which was set up by the Austrian government, said in a report issued on Tuesday. There also seemed to be “no awareness” that it had a responsibility for its students’ health.

The decision to effectively dismiss Ms. Noja-Nebyla was announced in a news release on Friday by the company that oversees all of Austria’s federal theaters.

The commission was set up in April after allegations of physical and mental abuse at the academy were revealed by Falter, an Austrian newsmagazine.
