The Crimean Tatar Mejlis is planning to appeal against a decision to ban the organization at the Russian Supreme Court, defense lawyer Jemil Temishev told Interfax.

"The decision is illegal and unsubstantiated. It is based less on the norms of the law and more on the principles of political expediency. Of course, an appellate complaint will be filed. The case will subsequently be heard at the Russian Supreme Court," the lawyer said.
