»EU-Regulation of the Audit Market. The Legality of the Regulation (EU) 53/2014 with Particular Focus on the Mandatory Audit Firm Rotation and the Prohibition of the Provision of Non-Audit Services« As a reaction to the financial crisis, the EU legislator adopted a regulatory reform of the audit market in June 2014. Its two main objectives are the improvement of audit quality and the alteration of established market structures. The reform contains two key measures: a system of mandatory rotation and a ban on the provision of non-audit services. This thesis tries to determine whether these measures are proportionate in terms of Article 52 of the Charter of Fundamental Rights of the EU.weiterlesen
