1. The law applicable to a non-contractual obligation arising out of an act of unfair competition shall be the law of the country where competitive relations or the collective interests of consumers are, or are likely to be, affected.
2. Where an act of unfair competition affects exclusively the interests of a specific competitor, Article 4 shall apply.
3. (a) The law applicable to a non-contractual obligation arising out of a restriction of competition shall be the law of the country where the market is, or is likely to be, affected.
(b) When the market is, or is likely to be, affected in more than one country, the person seeking compensation for damage who sues in the court of the domicile of the defendant, may instead choose to base his or her claim on the law of the court seised, provided that the market in that Member State is amongst those directly and substantially affected by the restriction of competition out of which the non-contractual obligation on which the claim is based arises; where the claimant sues, in accordance with the applicable rules on jurisdiction, more than one defendant in that court, he or she can only choose to base his or her claim on the law of that court if the restriction of competition on which the claim against each of these defendants relies directly and substantially affects also the market in the Member State of that court.
4. The law applicable under this Article may not be derogated from by an agreement pursuant to Article 14.
