File photo of Delhi High CourtNew Delhi- The Delhi High Court on Friday questioned the DGCA on the “indefinite” relaxation given to airlines with respect to the implementation of new norms on weekly rest and leaves for pilots. ADVERTISEMENTThe bench asked the Directorate General of Civil Association’s (DGCA) as well as IndiGo to file their response to the PIL in two weeks. DGCA counsel also said that a specific relaxation from night duty norms, through another letter issued on December 5, was given to IndiGo till February 10. The court, however, asked that when a temporary relaxation was given for night duty norms to IndiGo, why was the norm on non-substitution of weekly rest and leaves withdrawn without any deadline. And this applies to all airlines,” the court asked the DGCA counsel.
