Criminal Law Responses To Insider Trading In Stock Markets
🔹 1. Understanding Insider Trading
Insider trading refers to buying, selling, or dealing in securities based on unpublished price-sensitive information (UPSI) by individuals who have access to such information due to their position in a company.
It undermines market integrity, investor confidence, and fairness.
Key Ingredients
Insider: A person connected with the company (directors, employees, auditors, etc.).
Unpublished Price-Sensitive Information (UPSI): Non-public information likely to materially affect the price of securities.
Mens Rea (Criminal Intent): The knowledge that the information used was non-public and price-sensitive.
Actus Reus: The act of trading or communicating UPSI.
🔹 2. Legal Framework
(a) In India
Securities and Exchange Board of India Act, 1992 (SEBI Act)
Section 15G – Penalty for insider trading (civil liability).
Section 24 – Criminal liability: imprisonment up to 10 years or fine up to ₹25 crores, or both.
SEBI (Prohibition of Insider Trading) Regulations, 2015
Defines insider, UPSI, and duties.
Empowers SEBI to investigate, prosecute, and impose penalties.
(b) In the USA
Securities Exchange Act, 1934
Section 10(b) and Rule 10b-5 (SEC): prohibits fraudulent practices in securities transactions.
Criminal penalties: fines up to $5 million and imprisonment up to 20 years.
(c) In the UK

Punishable by imprisonment up to 7 years or unlimited fine.
Financial Services and Markets Act 2000 (FSMA) – Civil market abuse provisions.
🔹 3. Important Case Laws (Detailed Analysis)
Let’s now examine six landmark cases—Indian and international—where courts shaped insider trading law and criminal responses.
Case 1: Rakesh Agarwal v. SEBI (2003)
Citation: [2003] 57 CLA 29 (SAT)
Facts:
Rakesh Agarwal, Managing Director of ABS Industries, was negotiating a takeover by Bayer A.G. Before public announcement, his brother-in-law purchased ABS shares based on insider information.
Issue:
Whether such action amounts to insider trading under SEBI Regulations.
Held:
SAT observed that though there was a technical violation, Agarwal acted in the best interests of the company (to ensure takeover success).
Hence, no mens rea (criminal intent) was proved.
However, SEBI could impose civil penalties for breach of confidentiality.
Significance:
Established the need for intent and motive in insider trading prosecution.
Highlighted distinction between civil and criminal liability.
Case 2: Hindustan Lever Ltd. v. SEBI (1998)
Citation: [1998] 18 SCL 311 (Bom)
Facts:
Hindustan Lever Ltd. (HLL) purchased shares of Brooke Bond Lipton India Ltd. (BBLIL) before the public announcement of their merger. SEBI alleged insider trading since HLL was aware of merger information.
Issue:
Did HLL use UPSI before public disclosure?
Held:
Bombay High Court found no insider trading, as both companies were promoters and had mutual access to the information.
The merger was speculative information, not definitive UPSI at that time.
Significance:
Clarified what qualifies as unpublished price-sensitive information.
Emphasized the requirement of actual possession and misuse of UPSI.
Case 3: SEBI v. Cabot International Capital Corp. (2004)
Citation: [2004] 51 SCL 307 (Bom)
Facts:
SEBI imposed penalties on Cabot International for insider trading violations. The issue arose whether mens rea (criminal intent) is necessary for imposing penalties under SEBI Act.
Held:
Bombay High Court held that mens rea is not required for civil penalties.
But for criminal prosecution under Section 24 (imprisonment), mens rea is essential.
Significance:
Drew a clear line between civil and criminal liability.
Civil penalties may be strict liability, but criminal punishment requires intent.
Case 4: U.S. v. Martha Stewart (2003)
Jurisdiction: United States District Court, Southern District of New York
Facts:
Martha Stewart sold ImClone Systems shares after receiving insider information from her broker about the FDA’s rejection of a key drug.
Held:
Stewart was convicted for obstruction of justice and making false statements (not direct insider trading but related).
Sentenced to 5 months in prison and fined.
Significance:
Demonstrated how U.S. prosecutors use ancillary offenses (like obstruction, false statements) when direct insider trading proof is hard.
Sent a deterrent signal to corporate executives.
Case 5: SEC v. Raj Rajaratnam (2011)
Jurisdiction: United States Court of Appeals (Second Circuit)
Facts:
Raj Rajaratnam, founder of Galleon Group hedge fund, was accused of using insider tips from corporate insiders to earn millions.
Held:
Convicted under Rule 10b-5 for insider trading.
Sentenced to 11 years imprisonment and $150 million fine—one of the harshest sentences.
Significance:
Landmark case showing criminal enforcement strength in the U.S.
Introduced wiretap evidence as valid proof in insider trading cases.
Case 6: R v. McQuoid and Melbourne (2009)
Jurisdiction: UK Crown Court
Facts:
James McQuoid, a solicitor, learned about his firm's client’s takeover plans and tipped off his father-in-law, who traded in the target company’s shares.
Held:
Both were convicted under Criminal Justice Act 1993 for insider dealing.
McQuoid was sentenced to 8 months imprisonment; Melbourne (father-in-law) to 6 months.
Significance:
One of the first UK imprisonment cases for insider trading.
Demonstrated UK’s move from fines to custodial deterrence.
