1. What is Settlement Buy-In?

When you sell shares, you must deliver on pay-in day. If you don't, Clearing Corporation - NSCCL for NSE and ICCL for BSE - buys the shares on your behalf in a special auction session and delivers to the original buyer.

If a seller fails to deliver shares on T+1, a buy-in auction is triggered.

Current cycle in India is T+1 rolling settlement since Jan 2023.

Standard Timeline as per NSE / BSE Bye-laws:

• T Day: Trade execution
• T+1 Day, 10:30 AM: Securities pay-in deadline. Final obligation for securities pay-in is downloaded to members on T+1
• T+1 Day / T+2 Day - After pay-in: NSE Clearing conducts buying-in auction Historically T+2, now shifted to T+1 afternoon under T+1 regime.
• T+2 Day: Settlement of auction - buyer gets shares, defaulter pays difference.
• If auction fails: Shortage not bought-in are deemed closed out at close-out price = highest price from T to auction day + penalty.

For SLBM: Buy-in auction for failure of borrower to return securities is at 02:00 pm approx

BSE Clearing and Settlement note:

In case of default by the selling broker in a settlement, the security delivered short is bought in the auction session and is delivered to the buying broker

2. Obligation to Initiate Buy-In

The obligation is not on the defaulter broker alone, it is automatic by Exchange. But "Failure to Initiate Buy-In Process Within Required Timelines" occurs at 3 levels:

a) Broker level: Selling broker must report shortage, fund auction difference, and initiate internal buy-in against his client under SEBI circular MIRSD/SE/CIR-19/2009 - Policies and Procedures mandatory

Client shall be liable to penalty and other charges on... failure on payment of auction

If broker fails to initiate auction proceedings against client in time, it violates Code of Conduct for Stock Brokers.

b) Exchange / Clearing Corp level: If Exchange fails to conduct auction on scheduled time, it violates its own Bye-laws and SEBI Circular on close-out:

At the end of the settlement period... If a selling broker fails to make pay-in... the outstanding position is auctioned by the stock exchange

c) Corporate action cases: In case of bad delivery, objection cases under SEBI circular on Delay in transfer of shares- company must resolve within one month.

3. Consequences of Failure to Initiate in Time

1. Compulsory Close-Out: If buy-in not initiated, position is closed out at penal rate.
2. Financial Liability: Difference between trade price and auction/close-out price + auction charges borne by defaulter.
3. Penal Action under SEBI Act:
   • Section 15HB: Penalty of Rs 1 lakh minimum for failure to comply with any provision - used in adjudication
   • Section 15F: Stock broker penalties - Penalty of Rs 1 Lakh per day or 5 times brokerage
4. Disciplinary action by Exchange: Suspension, declaration as defaulter, withholding of pay-out.

4. Case Laws and SEBI / SAT Orders

While there is no single "Buy-In Timeline" statute, SAT and SEBI have repeatedly held that timelines must be strictly adhered to:

a) Pooja Vinay Jain Vs SEBI, SAT Appeal No. 152 of 2019
SAT held that delay in launching proceedings by SEBI cannot be a ground for exoneration. This principle is used against brokers who argue Exchange delayed auction.

Proceedings cannot be quashed merely for delay in launching: SAT

Same ratio reiterated in SEBI's own observation:

Action against violation of securities laws is not barred simply because of delay in initiating proceedings
Neither SEBI Act nor Regulations prescribe any time limit for initiating proceedings

b) SEBI vs Brokers for failure to maintain order placement and supervision leading to auction failures - SMC Global Securities (2024-25)
Thematic inspection found failure to maintain client order records and supervision of authorized person - fine Rs 1 lakh imposed. Such failures often lead to short deliveries and disputed buy-in.

c) SAT on Broker Norm Violations - Sunita Gupta (2013), Angel Broking (2023), NCJ Share & Stock Brokers
SAT upheld SEBI's penalty on brokers for violation of stock broker norms and fraudulent practices. In Angel Broking case, SEBI barred broker from taking new assignments for executing synchronized trades. Principle extended to settlement: if broker fails to initiate buy-in / close-out as per circular, it is violation of Regulation 26(vi) of SEBI (Stock Brokers) Regulations, 1992 - maintenance of discipline.

d) Cairn India Buyback Case - SAT Stay on SEBI penalties (2014)
Though corporate buy-back, it illustrates buy-back timeline breach importance. SEBI imposed Rs 5.25 cr penalty for misleading announcement regarding buyback of shares. SAT stayed but upheld principle that buy-back process must be monitored by company and broker.

e) SEBI Circular on Proceeds of Auction/Close-out
SEBI has standardized that if no offers received in auction, outstanding position compulsorily closed out as per standardized procedures. Failure to follow this by Exchange is irregular and can be challenged before SAT under Section 23L of SCRA.

5. Legal Defence / What Courts Check

1. Was shortage reported before 2 pm on T+1?
2. Did clearing member have clear funds by 8:30 am on settlement day?
3. Was auction conducted on same day after pay-in completion?
4. Is there evidence of mala fide in delaying buy-in to benefit from price movement?

If you are drafting a reply to Show Cause Notice for failure to initiate buy-in, take these grounds:

• No mens rea but operational error - penalty should be reduced under Section 15J factors
• Price difference already recovered from client, no loss to investor
• SAT in Man Industries Ltd vs SEBI (19 Jan 2023) held that proceedings must be initiated timely, else liable to be set aside only if undue delay prejudices defence
