2 Legal Effects of Blockade

1. On neutral ships: a vessel knowingly attempting to enter or leave a blockaded area is capturable (condemnable with cargo in prize — Unit 6's procedure); the liability attaches from notification and effectiveness (the vessel's knowledge presumed by the declared-and- notified blockade);2. On the voyage's continuity: breach of blockade as the continuous-voyage doctrine's second home (Unit 6 — the ultimate destination test applied to blockade-runners);3. On the cargo: condemnation's rule — the ship's breach taints the goods (the owner's innocence no defence in the classical law, mitigated by the insurance realities); contraband analysis runs alongside (Unit 6);4. On the belligerent: the duty of effective enforcement (paper blockades void — below), of notification (to neutrals and the local authorities), of impartiality within the blockade'sarea (no neutral-favouring exceptions), and the visiting-and-search proportionality (Hague XIII's restraints on force against neutral vessels);5. On third states: the neutral flag's rights preserved short of breach; the neutral state's duty of non-recognition of an invalid blockade and of protesting its commerce's interferences.
