<P>It is important to ensure that rights and obligations which constitute a financial instrument are not covered by the general rule applicable to consumer contracts, as that could lead to different laws being applicable to each of the instruments issued, therefore changing their nature and preventing their fungible trading and offering. Likewise, whenever such instruments are issued or offered, the contractual relationship established between the issuer or the offeror and the consumer should not necessarily be subject to the mandatory application of the law of the country of habitual residence of the consumer, as there is a need to ensure uniformity in the terms and conditions of an issuance or an offer. The same rationale should apply with regard to the multilateral systems covered by Article 4(1)(h), in respect of which it should be ensured that the law of the country of habitual residence of the consumer will not interfere with the rules applicable to contracts concluded within those systems or with the operator of such systems.</P>
