Litigants who have fought through trial courts and the High Court of Delhi are often surprised at the Supreme Court’s threshold rule: no advocate other than an Advocate-on-Record may act for a party there. The AOR system, rooted in Article 145 of the Constitution and the Supreme Court Rules, 2013, structures every filing in the Court — who signs the petition, who receives Registry communications, who is accountable for the record. This explainer sets out how the system works and how the professional team on a Supreme Court matter fits together.
Where the system comes from
Article 145 empowers the Supreme Court, with the President’s approval, to make rules regulating its practice and procedure, including “rules as to the persons practising before the Court.” The Supreme Court Rules, 2013 — continuing a scheme as old as the Court — divide advocates into three working categories: Advocates-on-Record, who alone may act for parties; advocates entitled to appear and plead when instructed by an AOR; and senior advocates, designated for distinction, who may plead but not act, and who appear only on the instructions of an AOR or another advocate. The design serves the Court’s functioning: a defined, examined, office-holding cadre answerable for every filing in a registry that processes tens of thousands of matters a year.
The AOR\'s functions across a matter\'s life
1. Certificate and filing
The AOR settles the SLP with counsel, certifies compliance with the Rules, files through the e-filing system, and answers the Registry\'s defect notices — the cure-and-refile cycle that precedes every listing.
2. Appearance and vakalatnama
The party\'s authorisation runs to the AOR; memos of appearance for arguing counsel route through the AOR\'s instruction.
3. Service and communications
All Registry communications, office reports and service of process flow to the AOR\'s registered office — the reason the Rules require one within the prescribed radius, staffed by a registered clerk.
4. Undertakings and compliance
Undertakings to the Court — on deposits, surrender, compliance affidavits — are given through and monitored by the AOR, whose accountability gives them credit.
5. Costs and accounts
The AOR is the advocate whose name enters the Court\'s record for taxation of costs and financial compliance in the matter.
The examination and what it signals
The AOR examination — held by the Court itself — tests practice and procedure of the Supreme Court, drafting, professional ethics, and leading cases. Its pass rates are famously exacting. For litigants, the signal is practical: the person signing the petition has demonstrated command of the Court’s own procedural law, from limitation and condonation practice to the anatomy of annexures, and maintains the infrastructure the Court requires. For the profession, the system creates a specialised procedural bar through which the wider bar — including counsel from every High Court — interfaces with the Court.
How teams are structured in practice
A typical SLP from a Delhi High Court matter involves three layers working together. The advocate who conducted the case below carries the factual memory — the record, the concessions, what was argued and what was not — and prepares the first draft or brief. The AOR converts it into a filing that survives the Registry: the correct paper book, the impugned order and annexures properly certified, the limitation position accurately stated, defects cured. Arguing counsel — sometimes the original advocate, sometimes a senior advocate briefed for the hearing — addresses the Bench. Nothing in the system displaces the client’s established professional relationship; it adds the procedural anchor the Court requires. The best outcomes come from early collaboration: an AOR consulted before the High Court order is even certified will shape the record with the SLP\'s requirements — synopsis, list of dates, questions of law — already in view.
- Timelines: the AOR needs the impugned judgment, pleadings below and the limitation calculation immediately — condonation applications weaken petitions.
- Candour: disclosure obligations in SLPs are strict; the AOR\'s certificate depends on the client\'s full instructions, including adverse orders and parallel proceedings.
- Communication: Registry notices go to the AOR — parties should keep a single instruction channel to avoid missed defects and dismissed-for-non-prosecution surprises.
Practice note: The AOR requirement applies to acting, not to advice. A litigant weighing whether a High Court defeat merits an SLP can and should take a merits opinion first; the AOR engagement then follows for the filing itself. The sequence keeps costs proportionate and ensures the decision to petition is made on the merits, not on momentum.
Frequently Asked Questions
What exactly may only an AOR do?
Act for a party: file appearances, petitions and applications, sign the pleadings, and take procedural steps. Under the Supreme Court Rules, an advocate who is not an AOR may plead — argue in court when instructed — but cannot act or file. Every SLP, counter affidavit and application in the Court therefore goes through an AOR who is answerable to the Court for it.
How does one become an Advocate-on-Record?
By qualifying under the Rules: broadly, requisite years of practice, one year of training with an AOR of prescribed standing, passing the Advocate-on-Record examination conducted by the Court (covering practice and procedure, drafting, advocacy ethics and leading cases), and maintaining a registered office within the prescribed distance of the Court with a registered clerk.
Does the client's existing lawyer become irrelevant?
No. The usual structure is collaborative: the advocate who conducted the matter below briefs the AOR, assists in settling the SLP, and frequently appears alongside; senior advocates are briefed for hearings through the AOR. The AOR anchors the filing and Registry interface while the litigation knowledge accumulated below remains central to the case.
Is the AOR responsible for the case's content?
Substantially, yes. The AOR's signature is not a formality: the Court holds AORs professionally accountable for the accuracy of the record, compliance with Rules, and the propriety of filings, and lapses can attract disciplinary consequences under the Rules including, in serious cases, removal from the register.
