(4)There is a need to establish a more uniform and stronger framework in order to preserve market integrity, to avoid potential regulatory arbitrage, to ensure accountability in the event of attempted manipulation, and to provide more legal certainty and less regulatory complexity for market participants. This Regulation aims at contributing in a determining manner to the proper functioning of the internal market and should therefore be based on Article 114 of the Treaty on the Functioning of the European Union (TFEU), as interpreted consistently in the case-law of the Court of Justice of the European Union.
