Fitting the Digital Markets Act in the existing legal framework: the myth of the “without prejudice” clause

Abstract

ABSTRACT The Digital Markets Act (DMA), an EU Regulation establishing obligations for gatekeeper platforms in order to protect fairness and contestability in digital markets, will soon start to apply. In addition to the DMA, other (EU and national) instruments regulate platform conduct. Though the DMA explicitly provides that it will apply without prejudice to those other instruments, it is doubted whether it will merely complement them. In certain cases, the DMA may qualify as lex specialis, thereby prevailing over other regulations. In other cases, based on the principle of supremacy, the DMA may override national instruments that pursue legitimate interests other than fairness and contestability. There may also be occasions where the DMA may render certain tools devoid of purpose when this was not the intention of the legislator. In all the above cases, the DMA would not complement (but could possibly endanger) the effectiveness of the existing regime. Given the avalanche of legislative proposals for platforms, addressing potential conflicts between the DMA and other rules is essential to protect legal certainty and to ensure that the regulatory regime that governs harmful platform conduct reaches its full potential.
