Constitutional interpretation clarifies application of the General Clauses Act and treats ordinances and foreign state references accordingly. Article 367 makes the General Clauses Act applicable to the interpretation of the Constitution, subject to specified adaptations, treats references to parliamentary or state Acts as including Presidential or gubernatorial Ordinances, defines 'foreign State' as any State other than India with provision for presidential determinations to the contrary, and prescribes specific interpretive adaptations for application of the Constitution in relation to Jammu and Kashmir, substituting historical references with references to the Governor and the State Legislative Assembly as appropriate.
