The Bombay High Court on Friday directed the Union government to file an affidavit in response to a public interest litigation (PIL) challenging the decision to make FASTag, the electronic toll collection chip, mandatory for all vehicles at toll plazas on national highways.

A bench of Chief Justice Dipankar Datta and Justice G S Kulkarni asked the government if there was any law that said all toll plazas at national highways across the country will only have FASTag lanes. The bench was hearing a PIL filed by one Arjun Khanapure, challenging the decision of making FASTag compulsory. The plea also challenged the government’s rule of imposing fines on vehicles flouting the FASTag rules.
