🌐 1. Introduction

A sandbagging clause is a contractual provision commonly found in mergers and acquisitions (M&A) agreements, which determines whether a buyer can make a claim for breach of representations and warranties even if the buyer knew about the inaccuracy at the time of signing.

A sandbagging prohibited clause is the opposite—it prevents the buyer from claiming damages if it had actual knowledge of a breach before closing.

Key purpose:

Protects the seller from claims where the buyer was aware of issues upfront.
Allocates risk between buyer and seller in M&A transactions.

⚖️ 2. Structure of Sandbagging Clauses

(a) Sandbagging Permitted

Buyer may bring claims even if aware of breaches.
Often benefits buyers by expanding remedies.

(b) Sandbagging Prohibited (No-Sandbagging)

Buyer may not bring claims for known breaches.
Protects sellers and reduces post-closing litigation.

(c) Key Considerations

Knowledge definition (actual knowledge vs. constructive knowledge)
Representations and warranties survival periods
Governing law: Common law vs. civil law jurisdictions treat sandbagging differently

🔍 3. Legal Principles

Actual knowledge matters: Courts often differentiate between a buyer’s actual knowledge and what it should have known.
Contractual freedom: Parties are generally free to decide whether to allow or prohibit sandbagging.
Allocation of risk: No-sandbagging clauses shift risk to the buyer if it chooses to proceed with known issues.
Jurisdictional differences: Some U.S. states (Delaware) and English law treat sandbagging clauses differently.
