The Academy of Motion Pictures Arts and Sciences is standing by its decision to oust accused rapist Roman Polanski from its ranks. Polanski sued the Oscars organization on Friday, and the Academy’s response was swift.

“The procedures taken to expel Mr. Polanski were fair and reasonable,” an Academy spokesperson said Friday afternoon. “The Academy stands behind its decision as appropriate.”

Here’s a snippet of Polanski’s filing in L.A. Superior Court: “The Academy committed a prejudicial abuse of discretion in that the Academy failed to proceed in a manner required by law, the Academy’s expulsion decision is not supported by the findings, and the Academy’s findings are not supported by the evidence.”
