The Maritime Labour Convention, 2006 (MLC 2006) was adopted by the International Labour Conference of the International Labour Organization (ILO), under article 19 of its Constitution, during a maritime session in February 2006 in Geneva. The aim of the current article is to analyze MLC regulation 5.2.1 regarding inspections in ports. In other words it will be discussed how member states which have ratified the MLC will enforce it through Port State Control (PSC) procedures.
