To answer, quote the clause, apply the facts, conclude.

Understand SEBI Act Prohibition on Substantial Acquisition (Section 12A)

Section 12A is the base prohibition in the SEBI Act for market abuse. It tells every person what they must not do in the securities market. The detailed rules sit in SEBI regulations, such as the PFUTP, Insider Trading and Takeover Regulations. Section 12A gives those regulations their statutory footing.

The section says "No person shall directly or indirectly" do six things, listed in clauses (a) to (f). Because of the words "directly or indirectly", it also catches acts done through relatives, friends, nominees or other entities.

Clauses (a) to (c) deal with fraud and manipulation. They cover manipulative or deceptive devices, schemes or artifices to defraud, and any act or course of business that operates or would operate as fraud or deceit. These apply in connection with the issue, purchase, sale or dealing in securities that are listed or proposed to be listed on a recognised stock exchange. Note that "would operate" means actual harm need not be proved.

Clauses (d) and (e) deal with information. Clause (d) bars insider trading. Clause (e) bars dealing in securities while in possession of material or non-public information, and bars communicating such information to any other person, in a manner that contravenes the Act, rules or regulations.

Clause (f) deals with control. No person may acquire control of a company, or securities beyond the percentage of equity share capital, of a company whose securities are listed or proposed to be listed, in contravention of regulations made under the Act. This is the takeover limb. The thresholds themselves are in the SEBI Takeover Regulations, not in the section.

Section 12A prohibits. The consequences come from other sections, for example Section 15G (penalty for insider trading), Section 15H (non-disclosure of acquisition), Section 11D (cease and desist) and Section 11 (SEBI's powers and measures).

Quoting takeover thresholds as if they are in Section 12A.

Worked examples

Example 1

Mr. Rao, a director of a listed company, learns of an unannounced merger. He tells his brother-in-law, who buys shares of the company before the announcement. Discuss with reference to Section 12A of the SEBI Act, 1992.

Show the solution

Provision: Section 12A(d) bars insider trading. Section 12A(e) bars dealing in securities while in possession of material or non-public information, and communicating such information to any other person, in contravention of the Act, rules or regulations.
Facts: Mr. Rao is a director with access to an unannounced merger, which is likely to be unpublished price sensitive information. The company is listed. He communicated it to his brother-in-law, who dealt on it.
Analysis: Mr. Rao's communication falls under clause (e) and, as an insider, he is exposed under clause (d). The brother-in-law dealt while in possession of the non-public information, so clause (e) applies to him too.
Consequence: Under Section 15G, an insider who communicates UPSI or deals on it is liable to a penalty of not less than ₹10 lakh, extending to ₹25 crore or three times the profit made, whichever is higher. SEBI may also pass orders under Section 11 and Section 11D.

Answer: Both Mr. Rao and his brother-in-law contravene Section 12A, clauses (d) and (e). Mr. Rao is liable to penalty under Section 15G, and SEBI may take further action under Sections 11 and 11D.

Example 2

A person acquires shares of a listed company and crosses the permitted percentage of equity share capital without following the Takeover Regulations. Is Section 12A attracted?

Show the solution

Provision: Section 12A(f) bars any person from acquiring control of a company, or securities beyond the percentage of equity share capital, of a company whose securities are listed or proposed to be listed, in contravention of regulations made under the Act.
Conditions: the company is listed, and the acquisition exceeds the permitted percentage without complying with the regulations.
Analysis: Both conditions are met. The act is a contravention of the regulations, so clause (f) is breached. The exact limit is found in the Takeover Regulations, not in Section 12A.
Consequence: SEBI may act under Section 11 and Section 11D. Section 15H provides a penalty for failure to make a required disclosure or open offer in an acquisition.

Answer: Yes. The acquisition violates Section 12A(f) because it exceeds the permitted limit in contravention of the Takeover Regulations. SEBI can take enforcement action and levy penalty.

Exam tips

Learn the six clauses as three groups: fraud (a to c), information (d and e), control (f). This helps in short notes.
Quote the opening words "No person shall directly or indirectly" and the phrase "listed or proposed to be listed" in every answer.
In fact-based questions, name the clause, apply it to the facts, then conclude. Do not stop at the section number.
Link Section 12A with Section 15G, Section 15H and Section 11D to show how the prohibition is enforced.
Do not quote takeover percentages as part of Section 12A. Refer to the Takeover Regulations for limits.
