Thus, if a ship, though neutral, be insured on a voyage prohibited by an embargo laid on in time of war, by the prince of the country in whose ports the ships happen to be, such an insurance is void.[31]

Similarly, all Insurances to protect the interests of British subjects trading without licence with the enemy are absolutely void.[32]

So also, if a Licence is not strictly pursued, so that the voyage becomes illegal, the insurance is void.[33]

I have said that all Insurances will be void which are designed to protect voyages or trading to hostile ports.  But, for this purpose, it must be clearly made out, not only that the port into which the ship sails is hostile, but also, that she was bound with a distinct hostile destination at the time of loss.  Thus a policy to “ports in the Baltic,” is legal, as some may be hostile, and some not, and it is not certain that she was sailing to a hostile port.

The general principle by which the validity of a policy is to be tested, is by the voyage, that it is a voyage prohibited by law, on some ground of public policy.  The will, therefore, of the parties is of no account, as the prohibition is for public, and not private benefit.  So that if the underwriter is told that the voyage is illicit he is not more bound than if he were not told so.[34]

It is Insurances upon voyages generally prohibited by law, such as to an enemy’s garrison, or upon a voyage directly contrary to an express act of parliament, or to royal proclamation in time of War, that are absolutely void and null;—­therefore, on neutral vessels, or the vessels of British subjects possessing neutral rights and sailing from neutral ports to enemies ports are not void.[35]

Similarly, with respect to Insurances on neutral vessels carrying contraband goods, for it is not the voyage, but the cargo, that is illegal in that case.[36]

Insurances are good on Neutral Vessels engaged in the Colonial Trade of the Enemy, and which was closed to the Neutral in time of peace,[37] It must be observed, that if a voyage is illegal, and voids the policy for that voyage, it does not follow that it voids the voyage in the opposite direction, and even the goods purchased by the proceeds of a former illegal voyage, may be the subject of Insurance.[38]

[Sidenote:  Bills of Exchange drawn during War.]

It has been stated above that all Bills drawn or negociated with the enemy, whether a British subject or the alien enemy be the acceptor, are null and void; during the last war, however, attempts were often made to draw and negociate bills that should pass muster in our courts of law, as for example:—­

An alien enemy, during war, drew upon a British subject resident in England, and who had funds of the alien in his hands; the drawer then indorsed the bill to an English-born subject, resident in the hostile country; such a bill cannot be enforced even after the restoration of peace, for otherwise it would enable alien enemies to take the benefit of all their property in this country, by allowing them to pay debts out of such funds, by the instrumentality of bills.[39]
