Beneficial penalty revisions can apply retrospectively to pending proceedings, Delhi High Court rules in pilot licence case

The petitioner, a pilot scheduled to operate Flight IX-1521 on 15 January 2026, underwent a pre-flight breath analyser (“BA”) examination and recorded a blood alcohol content of 0.014% in the first test.

On opting for alternate equipment, his second reading was 0.009% BAC.

Treating the result as a violation of Section 5, Series F, Part III of the Civil Aviation Requirements (“CAR”), the Joint Director General, DGCA, by order dated 11 February 2026, suspended his pilot licence for three months from 15 January 2026 and directed an endorsement on the licence.

The petitioner’s statutory appeal under Section 3B of the Aircraft Rules, 1937, was dismissed by the Director General of Civil Aviation on 28 April 2026.

During the pendency of the disciplinary proceedings, CAR Rev-05 was issued on 9 February 2026.

It prescribed counselling, without licence endorsement, for a first confirmatory BA reading up to 0.009% BAC.

Whether CAR Rev-05, which prescribed a lesser consequence for a first confirmatory BA reading up to 0.009% BAC, was applicable when the violation preceded the amendment but the final punishment order was passed after its issuance.

Whether the three-month suspension and licence endorsement imposed under CAR Rev-04 could be sustained where the petitioner’s reading was precisely 0.009% BAC and CAR Rev-05 was in force when the final order was passed.

The Court considered Rule 19(3)(a) of the Aircraft Rules, 1937, under which the suspension order was issued, and Section 3B of the Aircraft Rules concerning the petitioner’s appeal.

It applied the beneficial-construction principle to penal provisions, holding that an amendment reducing punishment should ordinarily benefit a person whose punishment remains under consideration.

Relying on T. Barai v. Henry Ah Hoe, (1983) 1 SCC 177, the Court reiterated that although an amendment enhancing punishment cannot be retrospectively applied, a reduced punishment may be given retrospective benefit to mitigate the rigour of the law.

The Court further held that this principle was not confined to criminal proceedings and could apply to the present regulatory disciplinary consequence.

Under CAR Rev-05, a first confirmatory BA reading up to 0.009% BAC attracted off-rostering and counselling, without endorsement on the pilot’s licence.

The Court distinguished between the date of the violation and the date on which the final punishment was imposed.

Although the petitioner’s BA test occurred on 15 January 2026, the final order was passed on 11 February 2026, two days after CAR Rev-05 had been issued.

Since the petitioner’s relevant reading was exactly 0.009% BAC, it fell within the threshold expressly covered by Rev-05.

Applying the beneficial-construction principle in T. Barai, the Court held that it would be unjust to impose the harsher three-month suspension and licence endorsement under Rev-04 when a lesser regulatory consequence was in force at the time the punishment order was made.

The Court therefore rejected the respondents’ contention that only the regulatory framework existing on the date of the violation could apply.

The impugned suspension order and the appellate order were set aside.

Although the petitioner had already undergone the three-month suspension, the Court directed that any endorsement relating to the BA violation be removed from his pilot licence.

The writ petition and pending applications were disposed of accordingly.
