Indian Courts have, for the most part been generous in applying International Law but recently, the Delhi High Court in AWAS Ireland v. Directorate General of Civil Aviation (W.P.(C) 671/2005, Judgment delivered on 19th March 2015, available here) marched a step ahead.
AWAS, which had leased aircrafts to Spice Jet, an Indian low cost carrier initiated writ proceedings in the Delhi High Court seeking de-registration of the leased aircrafts, upon termination of the lease agreements with Spice Jet for default in payment of lease rents. The High Court applying the Cape Town Convention on International Interest in Mobile Equipment, 2001 as also the Aircraft Protocol to the Cape Town Convention, to which India is a party, sanctioned de-registration of the aircrafts.
The Cape Town Convention and Aircraft Protocol have not been expressly, by legislation, adopted as a part of the Indian municipal law. All the same, the Supreme Court of India has, in plethora of cases including Aban Loyd Chiles Offshore v. UOI ((2008) 11 SCC 439; available here) consistently held that in the absence of municipal law, treaties can be looked into, if they are not in conflict with municipal law. In Vishaka v. State of Rajasthan ((1997) 6 SCC 241; available here) and National Legal Services Authority v. Union of India, ((2014) 5 SCC 438; available here), the Supreme Court of India applied international law even when then was no municipal law holding field in a certain area. In T.N.Godavarman Thirumulpad v. Union of India ((2012) 4 SCC 362; available here), the Supreme Court laid down a short but categorical directive – that treaties not contrary to municipal law are deemed to be incorporated in the municipal law. This was sufficient ammunition for India to apply the Cape Town Convention and the Aircraft Protocol.
While this is noteworthy, there is something else that makes the High Court judgment distinctive. In AWAS, the High Court ventured further. The High Court applied the principles enshrined in the Vienna Convention of Law of Treaties, 1969. What makes AWAS significant is that India is neither a signatory nor has it ratified the Vienna Convention. The High Court applying the principles of pacta sunt servanda in Article 26 and the general rules of interpretation of a treaty in Article 31 of the Vienna Convention, observed that an international convention is required to be interpreted in good faith, in accordance with the ordinary meaning given to the terms of the treaty, in their context, and in the light of its stated object and purpose. The High Court also applied the principle in Article 27 of the Vienna Convention which casts an obligation on a State to not only remain bound by the terms of a treaty entered into by a State but also, to not cite internal law as a justification for failure to perform its obligation under a treaty.
The Court did not debate whether the principles of the Vienna Convention constituted customary international law. This was evitable since the Supreme Court of India had, in Ram Jethmalani v. Union of India ((2011) 8 SCC 1; available here) already recognized that the Vienna Convention codifies many principles of customary international law.
AWAS marks a milestone, not only for India but also for the international community since principles engraved in the Vienna Convention, which are widely perceived as customary international law, have not just been acknowledged, but embraced by the High Court. AWAS is, without doubt, a small yet a significant contribution in the evolution of international law.
