Facts of the Case
-
The appellant, Rehana Khan, had engaged the respondent, Rizwan Siddiquee, an advocate enrolled with the Bar Council of Maharashtra and Goa, as her counsel during 2013–2014.
-
The appellant alleged that she had shared confidential personal information and material with the respondent concerning allegations against a senior police official.
-
A legal notice was subsequently issued to the police official through the advocate's office. The appellant disputed having authorised the notice, whereas the respondent maintained that it had been issued on her instructions.
-
On 24 July 2014, the appellant lodged an FIR against the police official under Sections 376(2), 376C, 354 and 354D IPC.
-
Thereafter, the respondent appeared in television interviews. During the broadcasts, conversations and material relating to the appellant were disclosed. The appellant alleged that the respondent had thereby violated his professional obligations and disclosed confidential information.
-
On 26 February 2015, she filed a disciplinary complaint under Section 35 of the Advocates Act, 1961 before the Bar Council of Maharashtra and Goa. The matter was subsequently taken up by the Disciplinary Committee of the Bar Council of India.
-
The Bar Council of India, by its order dated 11 August 2025, found professional misconduct and directed that the respondent's name be removed from the roll of advocates for two years, besides imposing monetary amounts.
-
Both parties challenged the disciplinary order before the Supreme Court.
Issues
-
Whether the finding of professional misconduct against the advocate was sustainable.
-
Whether the respondent's disclosure of confidential communications and information received from his client constituted professional misconduct.
-
Whether the respondent's participation in television interviews could be justified on the ground that he was responding to allegations made against him by his former client.
-
Whether the respondent had been denied a reasonable opportunity of hearing in the disciplinary proceedings.
-
Whether the punishment imposed by the Bar Council of India was inadequate and therefore required enhancement at the instance of the appellant.
-
Whether the conduct of both parties justified the imposition of costs by the Supreme Court.
Judgement
-
The Supreme Court upheld the disciplinary finding against the advocate.
-
The Court held that an advocate's professional duty of confidentiality does not disappear merely because the professional relationship with the client has broken down or because the client subsequently becomes adverse to the advocate.
-
The Court specifically found that the respondent had appeared on television and spoken about his relationship with the appellant and about information communicated between them. Recorded conversations and messaging material were also broadcast.
-
The Court rejected the justification that the advocate was merely responding to allegations against him. It observed that an advocate who believes himself to have been falsely accused has other legal remedies, including placing his version before the investigating agency or pursuing a defamation action.
-
However, the Court also found that the appellant herself had not been completely candid about relevant facts. Therefore, the Court declined her request to enhance the disciplinary punishment.
-
The Supreme Court ultimately dismissed all the connected proceedings and upheld the order dated 11 August 2025.
Held
The Supreme Court held, in substance, that:
-
An advocate cannot disclose or use confidential information received from a client against that client, even after the professional relationship has ended and even if the client subsequently becomes an adversary.
-
The Court found the finding of professional misconduct against Rizwan Siddiquee sustainable and declined to interfere with the disciplinary punishment.
-
The appellant's request for enhancement of punishment was also rejected because the Court found that she had not approached the Court with complete candour.
-
The Court further imposed costs of ₹5,00,000 each on the appellant and the respondent, payable to the Supreme Court Legal Services Committee within four weeks.
Analysis
-
The most significant principle emerging from the judgment is the strong protection given to confidential communications between an advocate and client.
-
The Court made it clear that the advocate's obligation is not conditional upon the client's subsequent conduct. The fact that the client later becomes hostile or adverse to the advocate does not give the advocate a right to disclose confidential information received during the professional relationship.
-
The respondent argued that he was facing public accusations and was therefore entitled to explain his position through the media.
-
The Court distinguished between legitimately defending oneself and publicly revealing privileged or confidential communications. According to the Court, the advocate could place his version before the investigating agency or pursue appropriate legal remedies, but could not use television interviews to disclose confidential communications.
-
The disciplinary proceedings were brought under Section 35 of the Advocates Act, 1961. The Bar Council had found that the disclosure of confidential information and public remarks concerning the client constituted professional misconduct.
-
The Supreme Court found that the disclosure established on the record was sufficient to sustain the disciplinary punishment.
-
The respondent argued that the disciplinary proceedings had proceeded without proper notice of the final hearing.
-
The Supreme Court rejected this argument after examining the record. The Court noted that the respondent had participated in the proceedings, entered an appearance, filed a written statement and participated in the recording of evidence.
-
The judgment also emphasises that a party seeking enhancement of relief must approach the Court with candour and complete disclosure of material facts.
-
The Court found that the appellant had herself appeared before the electronic media and had not fully disclosed certain circumstances surrounding the dispute. Consequently, the Court refused to enhance the punishment sought by her.
-
The Court strongly disapproved of the manner in which the dispute had continued for approximately eleven years, consuming the time of the Bar Council of India, the High Court and the Supreme Court.
-
Both parties were therefore directed to pay ₹5 lakh each as costs to the Supreme Court Legal Services Committee.
-
Client confidentiality is a fundamental professional obligation.
-
Confidential information cannot ordinarily be used against a former client.
-
Ending the advocate-client relationship does not automatically terminate the duty concerning information obtained during that relationship.
-
An advocate facing allegations must use appropriate legal remedies, rather than publicly disclosing confidential client communications.
-
Parties approaching constitutional courts must provide a complete and candid account of material facts.
-
Courts may impose substantial costs where the conduct of litigants unnecessarily prolongs proceedings and consumes judicial resources.
