Amit Kumar Yadav – Appellant
Versus
Union Of India – Respondent
LPA 595/2023
For the Appellants/Petitioners: Sanjeev Kumar, Anshul Sehgal

Aviation safety mandates concerning alcohol consumption are absolute; mandatory breath analyzer testing procedures, including control and secondary tests, are sufficient to ensure accuracy, and independent reports obtained outside the regulatory framework cannot invalidate standard pre-flight findings.
Headnote:(A) Aircraft Act, 1934 - Rule 133A of Aircraft Rules, 1937 - Civil Aviation Requirement (CAR) - Pre-flight breath analyzer (BA) test - Suspension of pilot license - Requirement of zero alcohol concentration for flight crew is non-negotiable - Procedural safeguards, including mandatory control tests and second tests for positive results, are sufficient to exclude claims of measurement error - Independent blood or urine tests, not conducted under the prescribed regulatory framework, are irrelevant for evaluating compliance with safety standards. (Paras 1, 13, 51, 55, 61)
(B) Writ Jurisdiction - Article 226 of the Constitution of India - Scope of judicial review - High Court cannot substitute its findings for those of the regulatory authority unless the impugned orders exhibit manifest perversity or material irregularity - Appellate interference is impermissible when the statutory procedure has been duly followed. (Paras 54, 61)
Facts of the case:
A pilot tested positive in a pre-flight breath analyzer test. Following established procedures, a control test and a second test confirmed the initial result. The pilot, contending the readings were false positives, submitted subsequent independent laboratory blood and urine reports showing negative results. The regulator suspended the pilot’s license for three months based on the breath analyzer results. The petition challenging the suspension was dismissed by the single Judge, leading to this appeal.
Findings of Court:
The court concluded that the regulatory framework for testing is self-sufficient with built-in safeguards, such as a mandatory control test to verify equipment serviceability. Independent test results obtained without official authorization hold no evidentiary value against the established regulatory procedure, which requires zero tolerance for alcohol in flight personnel.
Issues: Whether external independent blood and urine tests should invalidate regulatory breath analyzer results, and whether the reliance on specific pre-flight testing protocols was legally justified.
Ratio Decidendi: The court held that the aviation regulator’s prescribed testing procedures are designed to eliminate the possibility of error to the maximum extent. Since the pilot did not challenge the validity of the underlying regulations, and the record confirmed that every mandated procedural step was followed, the court refused to interfere with the suspension under its limited writ jurisdiction.
Result: Appeal dismissed.

JUDGMENT
V. KAMESWAR RAO, J.
1. This intra court appeal lays a challenge to the order dated 11.07.2023 passed by the learned Single Judge whereby the learned Single Judge has dismissed the writ petition filed by the appellant challenging the orders dated 04.12.2017 and 18.07.2018 (impugned orders) passed by the Joint Director General, Director General of Civil Aviation and Director General of Civil Aviation (respondent no. 2) respectively. Vide the Impugned Orders, the pilot license of appellant was suspended for a period of three months as per Regulation 8.1 of Civil Aviation Requirement (CAR) for testing positive for blood alcohol content in pre-flight breath analyzer test (BA Test).
2. The appellant is a pilot employed with Tata SIA Airlines Ltd. (hereinafter respondent no. 4/Vistara), which is running its Airline by the name of ‘Vistara Airlines’. The appellant was scheduled to operate a flight bearing No. 'UK 720' on 18.11.2017 from Kolkata to New Delhi, along with his senior, Captain Gurpreet Nijjer (hereinafter Capt. Nijjer). The estimated time of departure of the said flight was 07:10 am, so the reporting time of the petitioner was scheduled at around 06:00 am on 18.11.2017 at the Kolkata Airport.
3. The appellant reported at the Kolkata Airport and contacted paramedic nurse at 06:11 am for pre-flight breath analyser test as per the Regulations provided under CAR. The appellant was tested positive in the BA Test. The equipment used for conducting BA Test showed a reading of 0.004% alcohol in the blood of appellant.
4. The case of appellant as put forth by Mr Sanjeev Kumar is that he had not consumed any alcohol, sedative, narcotic or any stimulant drug. So, he was stunned when he got to know that his BA test was found positive. Between the first and second BA test, a control test was conducted on Capt. Nijjer as provided in CAR. After a while, a second BA test was conducted on the appellant which also turned out to be positive. Again, the equipment showed a reading of 0.004% blood alcohol content in blood of the appellant.
It is thereafter, the appellant was asked by Vistara Airlines to submit his pilot license for necessary action and he was also removed from flying roster following the procedure under the CAR.
5. The case of appellant is that after being removed from flying roster, he immediately visited two NABL accredited laboratories to undergo blood and urine tests for detecting presence of blood alcohol as he was apprehending that the equipment used for conducting BA Tests was prone to making errors. According to the appellant, the tests conducted were negative and the appellant sent an e-mail dated 21.11.2017 at 10:54 am to the Vistara Airlines informing them that he had undergone blood and urine tests at two NABL certified laboratories to prove his innocence. It was the case of the appellant that the concerned officials of the Vistara Airlines sent the letter dated 22.11.2017 to the Joint Director General and Director of Air Safety of DGCA respectively whereby they requested them to consider the BA test result of the appellant as negative, in view of the negative result of the blood and urine test of the appellant. It follows that the Vistara Airline suspended the appellant from his official duty for a period of three months w.e.f., 18.11.2017 to
