Allahabad High Court Applies 'Fruit of Poisonous Tree' Doctrine in Ravi Chaurasiya Illegal Detention Case

In a significant ruling that reinforces constitutional safeguards against illegal detention, the Allahabad High Court has held that a subsequent formal arrest and remand cannot cure an initial unlawful police custody. Applying the " fruit of the poisonous tree " doctrine, a division bench of Justice Atul Sreedharan and Justice Achal Sachdev ordered the immediate release of the corpus, Ravi Chaurasiya, and awarded ₹30,000 in compensation.

The Unlawful Custody That Sparked a Habeas Corpus Plea

Ravi Chaurasiya was taken into custody by the Soraon Police in Prayagraj from Ayodhya on September 14, 2026 at 9:00 PM. He was brought to the police station that same night but no arrest was recorded. His mother, concerned for his safety, visited the police station on September 15 , and a habeas corpus petition was filed before the High Court that very day. It was only on September 16 , after the petition was filed, that the police formally arrested Chaurasiya at 10:45 AM, recorded the arrest in the General Diary, produced him before a magistrate, and secured judicial remand.

A "Conscious Omission," Not an "Inadvertent Mistake"

The Station House Officer (SHO), Deen Dayal Singh, who was also the investigating officer, admitted in his counter affidavit that the failure to record Chaurasiya's presence in the police station's General Diary was an "inadvertent mistake." The Court rejected this explanation outright.

"This Court is unable to accept that the omission to show that the corpus was in their custody was merely an inadvertent mistake, and instead was a conscious omission by the Respondent to escape the charge of illegally detaining the corpus."

The Court noted that Chaurasiya had been held in police custody for over 24 hours without being produced before a magistrate, a clear violation of Article 22 of the Constitution.

The Poisonous Tree and Its Tainted Fruits

Drawing from American constitutional jurisprudence, the bench applied the " fruit of the poisonous tree " doctrine — but in a novel context. Traditionally used in evidence law, the court here applied it to arrest and detention.

"Where the initial action of unlawful detention itself was violative of the right of the corpus under Article 22, the same cannot be set right by a subsequent action of the police by formally arresting the corpus."

The illegal detention from 3:40 AM on September 15 to 10:45 AM on September 16 was the "poisonous tree." The subsequent arrest and remand were the "fruit," which the Court held were also illegal because they flowed from the initial illegality.

The bench relied on the Supreme Court's recent judgment in Jaskaran Jeet Singh Deol v. State of Punjab to hold that where an arrest is unconstitutional, subsequent remand orders and even the filing of a charge sheet cannot validate the arrest.

Pre-Arrest Duty to Inform of Right to Counsel

A key aspect of the ruling was the Court's interpretation of Section 38 of the Bharatiya Nagarik Suraksha Sanhita (BNSS) , which gives an arrested person the right to meet an advocate during interrogation. The High Court clarified that this duty arises even before formal arrest.

"Police cannot allow a process whereby, in order to escape the rigors of Section 38 BNSS, they do not arrest a suspect, call him to the police station, interogate him for 5-6 hours, and then make him an accused based on self-incrimatory statements."

The Court held that failure to inform the suspect of this right would vitiate all information provided by him, especially self-incrimatory statements.

Final Verdict: Release, Compensation, and Accountability

The Court ordered Chaurasiya's immediate release unless wanted in any other case. It directed the Commissioner of Prayagraj to conduct an inquiry into the illegal detention and fix responsibility on the erring officers. The Court also recorded its displeasure at the SHO's conduct, instructing that if negligence is found, the displeasure be entered in his service record.

The ₹30,000 compensation is to be recovered from those responsible for the illegal detention.

Key Observations

"Whenever a citizen is apprehended by the police, there is a legal and a constitutional duty on the police to ensure that his custody time is reflected in the G.D. from the time he is taken into custody."

"The fruit of the poisonous tree doctrine is applicable to the law relating to detention and arrest. The subsequent arrest and remand proceedings all stand vitiated by the application of the doctrine."

" Gross negligence is an intentional wrong doing based on the maxim ' culpa lata dolo aequiparatur '."

The petition was allowed and Chaurasiya was set free, marking a strong judicial check on police overreach and a reaffirmation of fundamental rights under Articles 21 and 22 of the Constitution.
