Palestinian lobby groups that contest Israel's authority over East Jerusalem have found they might be helped via an unexpected route: a French court. The court decided to take up the case against French companies contracted by Israel to build a tram line that runs deep into East Jerusalem from West Jerusalem…The group, Association France-Palestine Solidarité, filed the complaint against Alstom SA and Veolia Environnement SA two years ago, arguing that the 8.3-mile project violates international law because East Jerusalem isn't sovereign Israeli territory…Veolia and Alstom quickly responded to the complaint by saying that the Nanterre court had no jurisdiction over the case and that the association's claims were groundless. An official of the tribunal of Nanterre near Paris said the court ruled…that it does have jurisdiction in the case.
