In a remarkable case, The SC has upheld that due weight should be given to an order of child custody filed by the father in a foreign court.
Interim/interlocutory order for making child ward of court passed by foreign (UK) court of competent jurisdiction first in point of time deserves due weight and respect. Violation of such order by a parent should be viewed strictly as that would be destructive of rule of law and principle of comity of courts, although mere violation ought not to have penalising result. There must be some special reason, like want of jurisdiction of foreign court, for disregarding such order.. [Surya Vadanan v. State of T.N., (2015) 5SCC 450]
