In the Slovak case, the infringement procedure was originally initiated due to the fact that the Slovak car registration tax did not take into account the real value of second-hand cars purchased in another Member States. As a result, citizens paid a higher tax on such cars than on those second-hand cars purchased in Slovakia. Following action by the Commission, the Slovak authorities amended its legislation in February 2017 leading to a reduction in the tax levied on second-hand cars purchased in other Member States. In the Greek situation, the EU infringement procedure was originally opened to ensure the proper implementation of a judgement issued by the Court of Justice of the EU on car registration tax (case C-66/15: Commission v Greece). The ruling said that levying the full amount of registration tax on a car rented or leased by a Greek resident from a company established in another Member State - without taking into account the actual duration of the car lease - was inconsistent with EU law. Following the judgement, the Greek authorities amended its legislation to provide for a registration tax on cars based on the actual duration of the lease contract.
