The Bombay High Court on Wednesday issued a contempt notice to the pilots' union of Jet Airways for continuing the strike despite an earlier order restraining them.
The contempt notice was issued by Justice Dhananjay Chandrachud who sought a reply by September 14 on a petition by the airline.
A division bench of Chief Justice Swatanter Kumar and Justice A M Khanwilkar on Tuesday had restrained the pilots' union from continuing the strike.
Jet had moved the court after the pilots proceeded on sick leave en mass on September 7 to protest sacking of two of their colleagues.
Jet's lawyer had argued that going on sick leave in such a way was tantamount to strike.
Jet's contention is that pilots cannot go on strike when conciliation proceedings are underway under the provisions of Industrial Disputes Act.
