Sandbagging Doctrine

Definition:
The sandbagging doctrine allows a buyer in a contract—often in mergers and acquisitions (M&A)—to claim breach of a representation or warranty even if the buyer knew at the time of signing that the representation might be inaccurate. Essentially, it lets the buyer “sandbag” the seller by pursuing remedies despite prior knowledge.

Origin: Common in U.S. M&A practice, but increasingly recognized internationally.

Relevance of Sandbagging Doctrine

Protects Buyer Rights:
- Enables recovery for misstatements even when the buyer suspected or knew of the inaccuracy.
- Important in merger agreements and share purchase agreements (SPA).
Risk Allocation:
- Encourages clear contractual terms on representations, warranties, and indemnities.
- Parties can opt-in or opt-out of sandbagging via explicit contract clauses.
Due Diligence:
- Encourages sellers to be truthful and comprehensive in disclosures.
- Buyers are incentivized to conduct thorough due diligence.
Negotiation Leverage:
- Parties may negotiate “knowledge qualifiers” or “non-sandbagging clauses” to limit liability.
Legal Certainty:
- Courts often interpret the doctrine based on contract language, jurisdiction, and intent.
