licensees and transferees of rights and to prevent abuses, and taking into account that a certain amount of time is needed before a work or performance is actually exploited, authors and performers should be able to exercise the right of revocation in accordance with certain procedural requirements and only after a certain period of time following the conclusion of the licence or of the transfer agreement. Member States should be allowed to regulate the exercise of the right of revocation in the case of works or performances involving more than one author or performer, taking into account the relative importance of the individual contributions.
(81) The provisions regarding transparency, contract adjustment mechanisms and alternative dispute resolution procedures laid down in this Directive should be of a mandatory nature, and parties should not be able to derogate from those provisions, whether in contracts between authors, performers and their contractual counterparts, or in agreements between those counterparts and third parties, such as non-disclosure agreements. As a consequence, Article 3(4) of Regulation (EC) No 593/2008 of the European Parliament and of the Council should apply to the effect that, where all other elements relevant to the situation at the time of the choice of applicable law are located in one or more Member States, the parties' choice of applicable law other than that of a Member State does not prejudice the application of the provisions regarding transparency, contract adjustment mechanisms and alternative dispute resolution procedures laid down in this Directive, as implemented in the Member State of the forum.
(82) Nothing in this Directive should be interpreted as preventing holders of exclusive rights under Union copyright law from authorising the use of their works or other subject matter
for free, including through non-exclusive free licences for the benefit of any users.
(83) Since the objective of this Directive, namely the modernisation of certain aspects of the Union copyright framework to take account of technological developments and new channels of distribution of protected content in the internal market, cannot be sufficiently achieved by Member States but can rather, by reason of their scale, effects and cross-border dimension, be better achieved at Union level, the Union may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 TEU. In accordance with the principle of proportionality, as set out in that Article, this Directive does not go beyond what is necessary in order to achieve that objective.
(84) This Directive respects the fundamental rights and observes the principles recognised in particular by the Charter. Accordingly, this Directive should be interpreted and applied in accordance with those rights and principles.
(85) Any processing of personal data under this Directive should respect fundamental rights, including the right to respect for private and family life and the right to protection of personal data set out in Articles 7 and 8, respectively, of the Charter and must be in compliance with Directive 2002/58/EC and Regulation (EU) 2016/679.
(86) In accordance with the Joint Political Declaration of 28 September 2011 of Member States and the Commission on explanatory documents, Member States have undertaken to accompany, in justified cases, the notification of their transposition measures with one or more documents explaining the relationship between the components of a directive and the
