Whereas flag states are primarily responsible for living and labour conditions on board ships flying their flag, port state jurisdiction on board foreign-flagged ships is still uncertain from both a public and a private international law perspective. This paper focuses on the latter, to ascertain in which cases port state courts and domestic employment legislation decide on maritime employment contract matters. This may help to establish to what extent the extra-territorial exercise of port state jurisdiction is reasonable: adjudicatory jurisdiction and conflict-of-laws rules are construed on the basis of the proximity principle and thus strive to point out the state with the strongest link to the case at stake. However, the establishment of the port state legal system as the closest one to maritime employment usually amounts to setting the flag state aside, meaning that the subsidiarity principle takes over in determining the extra-territorial application of port state jurisdiction.

港口国对劳动条件的管辖权：域外法权的国际私法视角

尽管船旗国主要负责悬挂其国旗的船舶上的生活和劳动条件，但从国际公法和私法的角度来看，港口国对悬挂外国国旗的船舶的管辖权仍然不确定。本文侧重于后者，以确定港口国法院和国内就业立法在哪些情况下对海事就业合同事宜作出裁决。这可能有助于确定港口国管辖权的域外行使在多大程度上是合理的：裁决管辖权和法律冲突规则是在邻近原则的基础上解释的，因此努力指出具有最强联系的国家到案子。然而，
