船舶扣押是海商法领域颇具特色的制度。诉前扣押船舶具有建立管辖基础,为判决提供财产保全的作用。然而法院对船舶实施扣押的管辖权与对案件实体问题审理的管辖权并非一回事,两者既相互独立又密切联系,在一定条件下扣船管辖可以转化为实体管辖,但是要受到诸多因素的限制。 Seizure of ships is a distinctive system in the field of maritime law. The pre-voyage arrest of vessels has the function of establishing the basis of jurisdiction and providing property preservation for the judgment. However, the jurisdiction of the court to impose seizure on ships is not the same as the jurisdiction over the substantive issues of the case. Both of them are independent and closely linked. Under certain conditions, the jurisdiction of arrest may be transformed into substantive jurisdiction, but subject to many factors limits.
