A bench comprising Justices B S Chauhan and A K Sikri, however, made it clear that the Centre's decision on the joint venture between AirAsia India and Tatas will be "subject to the outcome of the case pending in the Delhi High Court".
It also asked the high court to decide the PIL, filed by BJP leader Subramanian Swamy, as early as possible without being influenced by observations made by the high court while dismissing his two interim pleas on the issue.
Swamy has moved the apex court against the February 11 order of the high court by which his two interim applications seeking a stay on grant of further approvals to operationalise the deal were rejected.
The high court, which has fixed the PIL for hearing on March 5, had said that the Centre was not "precluded" from "amending or clarifying" its FDI policy on aviation sector.
"The present petition entails interpretation of the policy by the government which created the policy. It cannot be lost sight of that even if the government was earlier of the view that FDI is to be permitted in existing airlines only, nothing prevented the government from subsequently allowing FDI in a new/proposed airline also and which is neither the subject matter of challenge nor can be the subject matter of judicial review.
"The policy was formulated by the government and the government cannot be precluded from clarifying or amending its policy which is executive in nature...," the high court had said.
Earlier, Swamy, on being ordered by the apex court, had filed the PIL in the high court seeking various reliefs including setting aside of all "approvals/permissions" granted to Tata, AirAsia India joint venture.
Later, he also filed two applications seeking interim relief of stay of impugned decision, taken on April 3, 2013, of the Centre and restraining it from granting any further approval/NOC to the joint venture.
