The measure creates a new legal basis to deny entry to specific vessels, increasing the likelihood of interdictions and forced rerouting before ships reach Italian ports. Operators and NGOs running rescue or transport missions face a longer potential exclusion window (up to six months), raising mission-planning costs and reducing the viability of repeated crossings on the same routes. The bill also widens the set of enforcement tools available to Italian authorities, increasing compliance and legal risk for maritime actors operating near Italy’s territorial waters.
