Microsoft has launched an attack on the European Commission, accusing it of disregarding evidence and denying due process.

In a response filed to the European Commission on Wednesday afternoon, the software giant explained why it believes that it has complied with the 2004 antitrust ruling.

In the filing, Microsoft claims that the EC had not reviewed the most recent documentation submitted by Microsoft, when the commission warned in December that Microsoft faced penalties for not providing “complete and accurate” specifications for the server interoperability information.

“When the commission issued its statement of objections on 21 December, 2005, the commission and its experts had not even bothered to read the most recent version of those documents which Microsoft had made available on 15 December, 2005,” the Microsoft filing stated.

Microsoft also claimed that is has not been given enough time to respond to the commission’s concerns and has therefore been “denied due process in defending itself.”
