ISLAMABAD: The Islamabad High Court (IHC) on Friday suspended the operation of a National Highway Authority (NHA) notification that imposed an additional 50 per cent toll on vehicles travelling on motorways without an M-Tag or with insufficient balance in their M-Tag accounts. The interim order was passed by IHC Justice Arbab Muhammad Tahir after hearing a petition filed by advocate Muhammad Jalal Haider, who had challenged the legality of the notification issued by the NHA on May 30, 2025. The court issued notices to the respondents, including the federation and the NHA, directing them to file a report and para-wise comments within a fortnight.
