External oversight of party and campaign funding is mainly regulated in Article 30 of the LPP and Articles 22, 38 and 65 ff. of the EC. This has been one of the main areas of concern for several years. For instance, the 2013 Joint Opinion noted that “overall, the lack of thorough scrutiny of previous campaign finance reports underscored the lack of an effective system in place and no official body that would be clearly responsible for verifying the accuracy of campaign finance reports and enforcement of campaign financing rules.” Similar concerns were raised with respect to general party funding by GRECO.
