Because the article does not reflect the latest status of this story, here is an update: The bank has now successfully filed a complaint against the withdrawal of the license and is now again a bank, although under supervision:

"In the first instance, the Administrative Court temporarily suspended the immediate effectiveness of the European Central Bank's (ECB's) withdrawal of the former Meinl Bank's licence until a final decision has been reached [...]. The parent company of the bank, Far East, had lodged a complaint, according to the court ruling." Source: https://wien.orf.at/stories/3022615/ (Own translation, article is in German)
