Capt Amit Kumar Yadav vs Union Of India & Ors.

Delhi High CourtJUDGMENT: May 04, 20263 MIN READSOURCE JUDGMENT
THE ORIGINAL LAWLENS SUMMARY
01

Facts

The Appellant, a pilot with Vistara Airlines, was scheduled to operate flight ‘UK 720’ on November 18, 2017

Source reference: p. 2

Upon reporting for duty, he underwent a pre-flight breath analyzer (BA) test which yielded a positive result of 0.004% blood alcohol content

Source reference: p. 2

Following Civil Aviation Requirement (CAR) protocols, a control test was conducted on another captain, followed by a second BA test on the Appellant, which confirmed the 0.004% reading

Source reference: p. 2

Consequently, the Appellant was removed from the flying roster and his license was suspended for three months

Source reference: p. 2

The Appellant subsequently underwent private blood and urine tests at NABL-accredited laboratories, which were negative, and challenged the suspension orders dated December 4, 2017, and July 18, 2018

Source reference: p. 3

A learned Single Judge dismissed his writ petition on July 11, 2023, leading to this intra-court appeal

Source reference: p. 1-2
02

Issues

1. Whether the results of private blood and urine tests conducted by a pilot independently can override the results of a mandatory pre-flight BA test conducted under CAR

Source reference: p. 7-8 / para. 48-49

2. Whether the BA test results were "false positives" due to equipment error or procedural lapses in the control test

Source reference: p. 8-10 / para. 51-52

3. Whether the DGCA is legally mandated to provide blood or urine testing as a confirmatory measure upon a positive BA test

Source reference: p. 10-12 / para. 53-55
03

Law Applied

The court applied Section 5 of the Aircraft Act, 1934, and Rule 24 of the Aircraft Rules, 1937, which prohibits crew members from consuming psychoactive substances and requires zero detectable blood alcohol

Source reference: p. 5, 11

It relied on Rule 133A of the 1937 Rules, under which the Civil Aviation Requirements (CAR) are issued

Source reference: p. 6

Specifically, CAR Section 5, Series F, Part IV (2015) governs the "Procedure for breath-analyzer examination," where Para 6.5 mandates a two-step BA test with a control test to eliminate equipment error

Source reference: p. 8, 12

Para 8.1 prescribes the penalty of a three-month license suspension for the first offense

Source reference: p. 15

The court also applied the principle of limited judicial review under Article 226 of the Constitution regarding technical expert findings

Source reference: p. 11, 17
04

Reasoning

The Court upheld the Single Judge’s reasoning that private tests conducted after the reporting time are irrelevant because the CAR requires a specific "zero" alcohol level at the exact time of reporting for duty

Source reference: p. 7-8, 15

The Court reasoned that the double-test procedure (two BA tests 15-20 minutes apart with an intermediate control test) is a robust mechanism designed specifically to eliminate "false positives" or equipment margins of error

Source reference: p. 8-9, 16

Regarding the "0.005% margin of error" plea, the court found that since the equipment produced a 0.000% result for the control subject and identical 0.004% results for the Appellant, its serviceability was verified

Source reference: p. 13-14, 16

The Court rejected the argument for mandatory blood/urine testing, noting that Rule 24 uses the disjunctive "or," implying any one of the three tests (breath, blood, or urine) is sufficient for enforcement; further, requiring blood tests for every flight is logistically and economically unfeasible for airlines

Source reference: p. 10-12, 18-19
05

Holding

It held that the CAR procedure was strictly followed and sufficiently rules out the possibility of error

The Court answered that private medical reports cannot supersede the statutory BA test conducted by the operator

Source reference: p. 15

The Court dismissed the appeal and upheld the three-month suspension of the Appellant's pilot license

Source reference: p. 21
