1. Unless otherwise provided by this Regulation or the statutes, the internal rules relating to quorums and decision taking in SE organs shall be as follows:
(a) quorum: at least half of the members must be present or represented;
(b) decision-taking: a majority of the members present or represented.
2. Where there is no relevant provision in the statutes, the chairman of each organ shall have a casting vote in the event of a tie. There shall be no provision to the contrary in the statutes, however, where half of the supervisory organ consists employees' representatives.
3. Where employee participation is provided for in accordance with Directive 2001/86/EC, a Member State may provide that the supervisory organ's quorum and decision-making shall, by way of derogation from the provisions referred to in paragraphs 1 and 2, be subject to the rules applicable, under the same conditions, to public limited-liability companies governed by the law of the Member State concerned.
