What is Amicus Curiae?
A 'friend of the court' — a non-party expert appointed by the court to provide unbiased legal assistance in complex cases.
Amicus Curiae is a Latin term meaning 'friend of the court'. It refers to a person, group, or organization who is not a party to a legal case but is appointed by the court — typically a senior advocate or domain expert — to offer information, expertise, or unbiased legal assistance. The amicus does not represent either side; instead, the role is to help the court arrive at a just decision, particularly in complex cases, Public Interest Litigations (PILs), suo motu proceedings, or cases where a party (often an indigent accused) is unrepresented. In India, the Supreme Court and High Courts frequently appoint senior advocates as Amicus Curiae under their inherent powers and the Supreme Court Rules, 2013.
Type: Concept- 1
Not a party to the case — The amicus has no personal or legal stake in the outcome and does not represent either the petitioner or the respondent
- 2
Appointed by the court, not hired by parties — Unlike a regular advocate, the amicus is requested by the judge through a formal order
- 3
Usually a Senior Advocate — In India, amicus appointments typically go to designated Senior Advocates with proven expertise in the relevant area of law
- 4
Provides neutral, unbiased assistance — Offers balanced legal analysis, often citing case law, statutes, and constitutional provisions to all sides of the issue
- 5
Generally pro bono — Serves without fees from parties; the court may direct a nominal honorarium from the State or Legal Services Authority in some cases
- 6
Used in complex or sensitive matters — Common in PILs, constitutional bench matters, suo motu cases, and criminal cases involving unrepresented accused
Must Remember
- Amicus Curiae literally means 'friend of the court' in Latin
- The amicus is NOT a party to the case and does NOT represent either side
- Appointed by the court (SC or HC), not selected by litigating parties
- Article 142 of the Constitution empowers the Supreme Court to pass any order for 'complete justice' — often the constitutional basis for amicus appointments
- Section 304 CrPC (now BNSS, 2023) and Article 39A relate to legal aid, frequently operationalised by appointing an amicus for unrepresented accused

The concept of Amicus Curiae originated in Roman law, where neutral experts assisted judges on complex points of law. It was absorbed into English common law and reached India through the colonial legal system. The institution gained real prominence in post-independence India with the rise of Public Interest Litigation in the late 1970s, when judges like P.N. Bhagwati and V.R. Krishna Iyer expanded the Supreme Court's role in protecting fundamental rights. Today, amicus appointments are routine in constitutional bench matters, environmental litigation, and human rights cases.

- 1
Step 1: Identification — The bench identifies a case needing amicus assistance (constitutional bench matter, PIL, suo motu case, or unrepresented accused)

Step 2: Selection — The presiding judge (often the CJI in major matters) selects a Senior Advocate known for expertise in the relevant area of law
- 3
Step 3: Formal Order — The court passes a written order appointing the advocate as Amicus Curiae and outlining the scope of assistance
- 4
Step 4: Case Study — The amicus studies pleadings, case files, relevant precedents, statutory provisions, and constitutional issues involved
- 5
Step 5: Submissions — The amicus files written notes/briefs and presents oral arguments before the bench, often distilling complex issues
- 6
Step 6: Independent Role — The amicus offers balanced views, which may sometimes go against the positions of all parties in the case
- 7
Step 7: Honorarium (if directed) — In long-running or labour-intensive matters, the court may direct the State or Legal Services Authority to pay a nominal fee

Amicus Curiae is a vital institution that strengthens the quality of justice in India. In Public Interest Litigations, where the petitioner may lack resources or specialised expertise, the amicus brings rigorous legal analysis to the bench. In suo motu cases — where the court itself initiates proceedings — the amicus becomes essential, as there is no formal petitioner. For unrepresented accused, especially the poor in criminal trials, the amicus operationalises the constitutional promise of free legal aid under Article 39A read with Article 21 (right to fair trial). More broadly, the institution upholds the integrity of the adversarial system by ensuring that complex matters of public importance receive expert input from neutral voices, not just from parties with vested interests. It also reflects the higher judiciary's evolution into a constitutional guardian rather than merely a dispute-resolution forum.

What does Amicus Curiae mean?
Amicus Curiae is a Latin term meaning 'friend of the court'. It refers to a neutral expert, usually a Senior Advocate, appointed by a court to assist it in deciding a complex case, without representing any party.
Who appoints Amicus Curiae in India?
The court itself — the Supreme Court of India or the High Courts — appoints the Amicus Curiae. The appointment is made by the bench hearing the matter through a formal order, and litigating parties have no role in this selection.
Can an Amicus Curiae represent a party in court?
No. An Amicus Curiae cannot represent any party to the case. The role is strictly neutral — to assist the court with legal expertise, precedents, and unbiased analysis, not to advocate for either side.
Is Amicus Curiae paid for their work?
Usually no. An Amicus Curiae typically serves pro bono (without fee). In long-running or labour-intensive cases, the court may direct the State or Legal Services Authority to pay a nominal honorarium.
What is the difference between Amicus Curiae and a Public Prosecutor?
A Public Prosecutor represents the State in criminal cases and argues for conviction of the accused. An Amicus Curiae is neutral — they neither prosecute nor defend, but assist the court with unbiased legal expertise.
