The Court considers that the Commission was correct to conclude that the work group server operating systems of Microsoft's competitors must be able to interoperate with Windows domain architecture on an equal footing with Windows operating systems if they are to be capable of being marketed viably.

The absence of such interoperability has the effect of reinforcing Microsoft's competitive position on the market and creates a risk that competition will be eliminated.

The Court observes that the circumstance relating to the appearance of a new product must be assessed under Article 82(b) of the Treaty. It considers that the Commission's finding that Microsoft's refusal limits technical development to the prejudice of consumers within the meaning of that provision is not manifestly incorrect.

Last, the Court rejects Microsoft's arguments to the effect that the refusal is objectively justified because the technology concerned is covered by intellectual property rights. The Court notes that such justification would render ineffective the principles established in the case law which are referred to above. The Court further considers that Microsoft has failed to show that if it were required to disclose the interoperability information that would have a significant negative effect on its incentives to innovate.

  • The Court therefore upholds the part of the decision concerning interoperability.

By way of preliminary observation, the Court considers that the factors on which the Commission based its conclusion that there was abusive tying are correct and consistent with Community law. It observes that those factors are as follows: first, the undertaking concerned must have a dominant position on the market for the tying product; second, the tying product and the tied product must be two separate products; third, consumers must not have a choice to obtain the tying product without the tied product; and, fourth, the practice must foreclose competition.

In respect of each of those factors, the Court considers that the Commission's decision is well founded.

First, the Court observes that it is not disputed that Microsoft had a dominant position on the client PC operating systems market.

Second, the Court, noting that that the question as to whether products are distinct must be assessed by reference to consumer demand, finds that a number of factors based on the nature and the technical features of the products concerned, the facts observed on the market, the history of the development of the products concerned and also Microsoft's commercial business practice, demonstrate the existence of separate consumer demand for media players. In that regard, the Court notes, inter alia, that the Windows operating system is system software, whereas Windows Media Player is application software; that there are independent companies, like RealNetworks, who design and supply competing products independently of operating systems; that Microsoft develops and markets Windows Media Player for other operating systems; that Windows Media Player can be downloaded independently of the Windows operating system; and that, in spite of the bundling, a not insignificant number of consumers continue to acquire competing media players separately.

Third, the Court observes that it is beyond dispute that, in consequence of the tying, consumers are unable to acquire the Windows operating system without simultaneously acquiring Windows Media Player. In that regard, the Court considers that neither the fact that Microsoft does not charge a separate price for Windows Media Player, nor the fact that consumers are not obliged to use that media player, is relevant for the purposes of the examination of that factor.

Fourth, the Court finds that the Commission clearly demonstrated in the contested decision that the fact that Microsoft offered OEMs only the version of Windows bundled with Windows Media Player had the inevitable consequence of affecting relations on the market between Microsoft, OEMs and suppliers of third-party media players by appreciably altering the balance of competition in favour of Microsoft and to the detriment of the other operators. The Court considers that that practice enabled Microsoft to obtain an unparalleled advantage with respect to distribution of its product and to ensure the ubiquity of Windows Media Player on client PCs throughout the world, thus providing a disincentive for users to use third-party media players and for OEMs to pre-install such media players on client PCs. The Court concludes that the Commission was correct to find that there was a significant risk that the tying would lead to a weakening of competition in such a way that the maintenance of an effective competitive structure would not be ensured in the near future.

Last, the Court finds that Microsoft has not demonstrated the existence of objective justification for the bundling and that the remedy imposed by the Commission is proportionate. On that point, the Court makes clear that Microsoft retains the right to continue to offer the version of Windows bundled with Windows Media Player and that it is required only to make it possible for consumers to obtain the operating system without that media player, a measure which does not mean any change in Microsoft's current technical practice other than the development of that version of Windows.

  • The Court therefore upholds the part of the decision concerning the bundling of Windows Media Player.

The Court observes that if the Commission decides to seek the assistance of an external expert, it may communicate to him all the information and documents which it has obtained in the exercise of its powers. However, it considers that by establishing the mechanism of a monitoring trustee, with his own powers of investigation and capable of being called upon to act by third parties, the Commission went far beyond the situation in which it appoints its own expert to advise it during an investigation.

The Court criticises, in particular, the obligation imposed on Microsoft to allow the monitoring trustee, independently of the Commission, access to its information, documents, premises and employees and also to the source code of its relevant products. It observes that no limit in time is envisaged for the continuing intervention of the trustee.

The Court finds that the Commission has no authority to compel Microsoft to grant to a monitoring trustee powers which the Commission itself is not authorised to confer on a third party.

Last, the Court considers that the Commission exceeds its powers insofar as it makes Microsoft responsible for all the costs associated with the monitoring trustee. There is no provision of Community law that authorises the Commission to require an undertaking to bear the costs which the Commission itself incurs as a result of monitoring the implementation of remedies.

The Court therefore annuls the decision insofar as it orders Microsoft to submit a proposal for the appointment of a monitoring trustee with the power to have access, independently of the Commission, to Microsoft's assistance, information, documents, premises and employees and to the source code of the relevant Microsoft products and insofar as it provides that all the costs associated with that monitoring trustee be borne by Microsoft.

  • The fine

The Court finds that the Commission did not err in assessing the gravity and duration of the infringement and did not err in setting the amount of the fine. Since the abuse of a dominant position is confirmed by the Court, the amount of the fine remains unchanged at €497 million. [17 September 07]
