A bench headed by Justice B S Chauhan said it was not making any observation on merits of the matter and asked Swamy to move the high court which can hear him in detail.
"We want to have advantage of high court judgement," the bench said while giving him liberty to file the public interest litigation (PIL) in the high court.
Swamy told the court he was not challenging the policy but questioning the action which has been taken by the government under the policy.
AirAsia India will be based in Chennai in which the Malaysian carrier will hold a 49 per cent stake. Initially, AirAsia plans to invest USD 30 million in the company.
In his PIL, Swamy has challenged the clearance granted to the proposed airline on the ground that according to the policy, foreign investment is only permitted for an existing airline but AirAsia India was not an existing carrier.
