Case C-264/23 Booking.com – Ancillary restraints and market definition in the platform economy

The recent judgment of the CJEU in Booking.com represents yet another development in the long series of cases concerning price parity clauses in the platform economy. In Booking.com’s case, the judgment represents the end of the line for its parity clauses. In its greater context of applying EU competition law in the digital economy, the judgment offers new insights into […]

Booking / eTraveli: assessing envelopment strategies and mixing up market power thresholds

About a month ago the European Commission announced that it was prohibiting the acquisition of eTraveli by Booking Holdings (Booking.com). The prohibition, which is a rare occurrence in itself, did not attract much attention beyond comments on the ‘ecosystem’ theory of harm which it may have introduced. But this case offers more than that. First, it shows that current practice […]

The ECJ Judgment in CK Telecoms – Setting the Record Straight?

Introduction On 13 July 2023, the European Court of Justice (‘ECJ’) delivered its highly anticipated ruling in CK Telecoms UK Investments v European Commission (‘CK Telecoms’). The Grand Chamber judgment is significant at the most fundamental level. It clarifies some of the core legal concepts and principles at the very heart of EU merger control. The five crucial issues the […]

Case C-42/21P Lithuanian Railways – another clarification on the Bronner case law and the non-exhaustive character of art. 102 TFEU

The recent case of Lithuanian Railways provides yet another clarification on the scope of application of the Bronner case law. The Judgement of the CJEU reconfirms exceptional character of the Bronner case law and the type of situations it is intended to apply to. By doing so the CJEU potentially helps prevent future disputes of a similar  nature in the […]

On-platform Tying or Another Case of Leveraging- A Discussion on Facebook Marketplace

Just before 2022 ended the Commission sent a statement of objections to Meta regarding the potential abusive behaviour of Facebook. According to the statement of objections, Facebook may be engaging in (i) abusive tying practices with regard to Facebook Marketplace as users (i.e. consumers) that log into Facebook and are automatically also offered access to the Facebook Marketplace, without the […]

The draft notice on market definition and multisided (digital) platforms – avoiding rather than resolving some of the main challenges

Approximately a month ago the Commission published its draft notice on the definition of the relevant market. The new notice is supposed to replace the old one that dates back to 1997 and thereby bring the entire process up to date with today’s new challenges, particularly in the context of digital markets. A first read of this long awaited document […]

Amazon cases on the move: Bundeskartellamt closes proceedings while European Commission opens formal investigation

The 17th of July has been quite the day for Amazon, at least when it comes to antitrust. Firstly, the German Competition Authority (Bundeskartellamt) has closed its abuse of dominance proceedings against Amazon in return for concessions from the online marketplace. Secondly, the European Commission announced that it was opening a formal investigation into possible anti-competitive conduct by Amazon. This blog post takes a closer […]

App stores and (potential) abuses of dominance – an opportunity to reshape competition law enforcement in digital markets

During the past few weeks the number of complaints against Apple’s practices concerning the App Store has not gone unnoticed. While previous complaints by unhappy developers were perceived as isolated cases it would seem that now the flood gates have been opened, and the stream is primarily targeting Apple. In Europe, this development has been given quite some media coverage […]

Business users vs. platforms – a (not entirely) new battle frontier

The recent complaint of Spotify against Apple is yet another case concerning the contractual relationship between online platforms and their business users that appear to arise quite often these days. In the context of these cases the business users of online platforms claim to be subject to undesired practices such discriminatory treatment and unreasonable pricing. The essence of most of these complaints […]

When competition law met data protection: the Bundeskartellamt’s Facebook decision

On February 6th, the German Competition Authority (Bundeskartellamt or BKA) adopted its long-awaited Facebook decision, imposing far-reaching restrictions on how the social network can collect and process user data. This decision follows a preliminary assessment that the BKA published in December 2017, which this blog discussed at length. The BKA’s decision—as set out in a case summary and background paper—sticks closely to its preliminary assessment. In this blog post, […]
