The market impact of the Convention on civil litigation in the six original Member States was a matter of concern with several speakers. It was stressed in particular that the mere solution of jurisdictional problems may require extensive research of substantive issues, which possibly could lead to litigation at three national levels. If the possibility of submitting preliminary questions under the 1971 Protocol to the EC Court at Luxemburg is also taken into account, five judgments could even be required to settle the question which court in the Common Market is competent. Although perhaps inspiring lawyers' intellectual efforts, this situation would unfortunately increase the litigation costs to the parties. Moreover, the final text of the EC Draft on the law applicable to contractual and non-contractual obligations is progressing and the EC Court will be charged with ensuring the uniform interpretation of this convention as well. One can imagine questions being put to the European Court in each of the three stages of a dispute, viz., the jurisdiction phase, the applicable law, and the enforcement in another Member State.
