The question for determination is whether the operation of sec. 5
of the Act extends to the obligation to pay interest arising under
the deeds and debentures already mentioned. That depends upon
the interpretation of the section. The words of the enactment are
general, and in themselves suggest no limitation, unless the words
"deemed to be satisfied ' - not " satisfied ' - indicate that the
Legislature contemplates satisfaction within its territory, whatever
happens in other States and countries. But it is contended that
the Act must receive some limitation, to avoid conflict with the rules
which govern the extraterritorial recognition of rights, and the
choice of the law with reference to which the rights of the parties
are determined. Thus, according to the law administered in English
Courts, that which measures and defines " the rights and liabilities
of the parties to a contract " is the law or laws to which the parties
intended, or may fairly be presumed to have intended, to submit
themselves, or the proper law of the contract (Foote, Private Inter-
national Law, 5th ed. (1925), p. 423; Hamlyn & Co. v. Talisker
Distillery (3) ). The validity of the discharge of a contract therefore
depends upon this law. A discharge in accordance with the proper
law of the contract is accordingly said to be valid, whilst a discharge
not in accordance with that law is invalid (Dicey, Conflict of Laws,
4th ed. (1927), p. 637). But, as Dicey says at p. 637, "all that
can be absolutely laid down is that when a contract is made and
to be performed in the same country, anything which discharges
the liability under the law of that country will be held a good
discharge by our Courts." (Cf. Story, Conflict of Laws, 1834 ed., pp-
280, 480; Foote, Private International Law, 5th ed. (1925), p. 483.)
Again, it is said that the performance of a contract, when a special
place for performing it is expressly or impliedly agreed upon, is
regulated as to mode, time, and condition by the law of that place
(Chatenay v. Brazilian Submarine Telegraph Co. (4); Jacobs v.
