"Microsoft’s request for this emergency ex parte relief is not the result of any lack of diligence on Microsoft’s part, but instead based upon the nature of Defendants’ unlawful conduct. Therefore, in accordance with Federal Rule of Civil Procedure 65(b) and Civil Local Rule 7-5, good cause and the interest of justice require that this Order be Granted without prior notice to Defendants, and accordingly, Microsoft is relieved of the duty to provide Defendants with prior notice of Microsoft’s motion." (Microsoft's motion in question being their attempt to seize the domains.)

The basis for this was "unlawful and/or negligent conduct". Basically, Microsoft managed to convince the courts that because in their eyes No-IP weren't policing their services well enough, Microsoft had the right to seize all their domains and shut them down without giving them the opportunity to challenge this in court first.
