Parties and procedural roles: This was not a conventional plaintiff-versus-defendant suit. The Supreme Court initiated the case suo motu; the institution of the Court acted to protect the administration of justice, and Justice C.S. Karnan was the alleged contemnor/respondent whose publications, orders and non-compliance were examined. In Indian Supreme Court terminology, these parties are therefore described as petitioner/appellant and respondent, accused/prosecution, or contemnor/Court as appropriate—not automatically as plaintiff and defendant.

Detailed factual and procedural background: This was a suo motu contempt proceeding by the Supreme Court against sitting Calcutta High Court judge C.S. Karnan. The Court treated his public allegations, purported judicial orders against Supreme Court judges, and repeated refusal to appear as attacks on the administration of justice; Justice Karnan maintained that the proceedings were discriminatory and beyond the Court’s power.

How the dispute reached the Court: The proceeding numbered SMC(C) No. 1/2017 developed through the events recorded in the timeline: January–May 2017: Justice C.S. Karnan circulated accusations against judges and defied repeated Supreme Court directions. 8 February: seven-judge bench initiated suo motu contempt. 1 May: medical examination ordered but not completed. 9 May: conviction and six-month sentence. The concrete problem was not merely academic; it required the Court to decide: Can the Supreme Court punish a sitting High Court judge for contempt? Did the respondent’s publications, counter-orders and disobedience constitute criminal contempt, and what procedure and sanction were lawful?

The Court considered whether a sitting High Court judge is subject to Supreme Court contempt jurisdiction and whether the conduct scandalised the judiciary or obstructed justice. Justice Karnan challenged jurisdiction, alleged caste bias and sought to continue issuing counter-orders; the Attorney General and assisting counsel stressed institutional integrity and compliance with binding orders.

Expanded comparison of the competing positions: The side seeking relief asked the Court to apply Contempt jurisdiction; equality before law; judicial accountability; protection of administration of justice to the actual institutional or individual harm shown by the record. The opposing side relied on statutory authority, procedural regularity, governmental necessity, finality or administrability, depending on the proceeding, and urged a narrower remedy. Both positions had to be tested against Constitution of India; Contempt of Courts Act, 1971; Supreme Court Rules, 2013 and Articles 129, 142 and 215.

What the Court had to evaluate: It examined the text and purpose of the governing provisions, binding precedent, the evidentiary or institutional record, and the practical consequences of accepting either interpretation. The decisive questions were: Can the Supreme Court punish a sitting High Court judge for contempt? Did the respondent’s publications, counter-orders and disobedience constitute criminal contempt, and what procedure and sanction were lawful?

The seven-judge bench unanimously convicted Justice Karnan of contempt and sentenced him to six months’ imprisonment. It held that constitutional office does not confer immunity from contempt jurisdiction; his acts gravely damaged the judiciary and obstructed justice. A later reasoned opinion explained the institutional and procedural basis.

Reasoning and legal effect: The result followed from the Court’s application of Contempt jurisdiction; equality before law; judicial accountability; protection of administration of justice to Constitution of India; Contempt of Courts Act, 1971; Supreme Court Rules, 2013 read with Articles 129, 142 and 215. The Court distinguished the legal rule binding future courts from observations confined to the facts, and tailored the operative relief to the procedural posture of IN RE vs HONBLE MR JUSTICE C.S. KARNAN.

Practical consequence: The parties are bound by the operative directions in SMC(C) No. 1/2017; lower courts, governments, regulators or investigating authorities must apply the stated ratio in materially similar cases. Any prospective limitation, remand, monitoring direction, bail condition, implementation safeguard or preservation of concluded matters mentioned above forms part of the scope of the ruling. The signed judgment remains controlling if a short summary and the operative paragraphs differ.
