Court overturns Win 95-browser injunction

Court overturns Win 95-browser injunction

A US court yesterday overturned an injunction that prevented Microsoft from requiring computer makers that use its Windows 95 operating system to also use its Internet Explorer Web browser.

The US Court of Appeals for the District of Columbia ruled that a lower court made both procedural and substantive errors in imposing the injunction. One judge on the three-judge panel dissented on part of the opinion that dealt with whether the lower court had made substantive errors, but agreed with the majority that the injunction should be overturned on procedural grounds.

The US Department of Justice said it is disappointed with the appellate court decision and is reviewing its options. "We remain confident that the evidence and our legal arguments in our antitrust case filed on May 18, 1998 will demonstrate that Microsoft's conduct has violated federal antitrust laws," the agency said in a statement.

The May lawsuit argues that Microsoft is using its dominance in the operating system market to unfairly gain advantage in the browser and Internet market by bundling its Internet Explorer browser with Windows 98.

Microsoft predicted that yesterday's decision would affect the outcome of the broader case involving Windows.

"This is a great day for consumers. Today's decision affirms the central principle Microsoft has been defending that every company should have the freedom to improve its products and integrate new features on behalf of consumers," the company said in a statement. "Both of the Government's lawsuits are based on the same argument, rejected yesterday by the Appeals Court, that Internet Explorer is separate from Windows. So we believe this ruling will be very helpful to provide guidance to resolve the Window 98 lawsuit."

The Appeals Court also granted a Microsoft request that it require the district court to revoke or revise its assignment of the matter of a permanent injunction to a special consultant to the court, dubbed "special master".

"We find that the District Court erred procedurally in entering a preliminary injunction without notice to Microsoft," according to the majority opinion published on the court's Web site (

District Judge Thomas Penfield Jackson also erred "substantively" is his reading of a 1995 consent decree between Microsoft and the US Department of Justice, according to the Appeals Court.

The Appeals Court said the union of Windows 95 and Explorer is "a genuine integration" and that Microsoft is not prevented from offering the browser as an integrated product.
