This chapter discusses restrictions to the enforcement of foreign laws under Indian law. Section 23 of the Indian Contract Act, 1872, forbids an Indian court from recognizing or enforcing a contract where such recognition or enforcement would be opposed to Indian public policy, or where such contract was obtained by fraud. A well-known principle of conflict of laws is that a court will not enforce a foreign penal law, either directly or indirectly. Foreign revenue laws are comparable to foreign penal laws from the standpoint of enforceability. As a matter of principle, a court will not enforce the public law of a foreign country, though the scope and ambit of this principle remains nebulous.
