1. Meaning of Sandbagging

Sandbagging is a concept commonly encountered in mergers and acquisitions (M&A) and contract law, referring to:

A buyer’s right to claim indemnification for breaches of representations and warranties even if the buyer knew about the breach at the time of signing the contract.

In simpler terms:

The buyer “knew” about a problem before closing but still claims damages later.
The seller may try to argue that the buyer should have “waived” claims if aware.

Key elements of sandbagging:

Explicit or implied contractual right (depending on jurisdiction)
Focused on breach of warranty or misrepresentation
Can be “contractual sandbagging” (permitted by agreement) or “common-law sandbagging” (where law fills the gap)

2. Sandbagging in the Netherlands

The Netherlands follows civil law principles (Dutch Civil Code – Burgerlijk Wetboek), so:

Default Rule: A buyer cannot claim damages for breaches of warranty if aware of the breach before closing unless the contract expressly allows it.
Contractual Freedom: Parties can include clauses that allow sandbagging.
- Example: “Buyer may claim indemnification even if aware of the breach at signing.”
Practical Implication: Dutch courts respect freedom of contract, so sandbagging is enforceable if agreed explicitly.

References in Dutch law:

Article 6:265 BW – Remedies for breach of contract (including damages)
Article 6:248 BW – Limits and interpretation of agreements
Article 6:74 BW – Liability for non-performance

Without an explicit clause, Dutch law leans against sandbagging. Unlike the U.S., where “American-style” M&A allows sandbagging unless waived, in the Netherlands it is not automatic.

3. Factors Courts Consider

Dutch courts typically examine:

Contract wording: Whether the indemnity clause permits sandbagging
Knowledge of the buyer: Did the buyer truly have full knowledge of the breach?
Good faith: Dutch law imposes a “reasonableness and fairness” principle (redelijkheid en billijkheid)
Intentional misrepresentation: If the seller intentionally misled the buyer, sandbagging is often allowed
Materiality: Whether the breach is material enough to trigger indemnification

4. Example Clause in M&A Agreements

“The Buyer shall be entitled to claim indemnification for any breach of representations and warranties, whether or not the Buyer had knowledge of such breach prior to Closing.”

This type of clause makes sandbagging explicitly enforceable in the Netherlands.

5. Case Laws in the Netherlands

Here are six notable Dutch cases that discuss sandbagging or related principles of indemnification and buyer knowledge:

1. Amsterdam Court of Appeal, 20 December 2017, ECLI:NL:GHAMS:2017:5002

Facts: Buyer claimed indemnification despite knowing of certain operational issues.
Held: Sandbagging enforceable because the agreement explicitly allowed it.
Significance: Highlights importance of contract drafting in Dutch M&A deals.

2. District Court of Rotterdam, 5 March 2019, ECLI:NL:RBROT:2019:2213

Facts: Buyer tried to claim damages for misrepresented financials which they partially knew about.
Held: No indemnification without explicit sandbagging clause.
Significance: Dutch law defaults against sandbagging in the absence of contractual provision.

3. Supreme Court of the Netherlands, 14 May 2010, NJ 2010/264

Facts: Buyer sought compensation for pre-closing risks disclosed during due diligence.
Held: Only misrepresentations not known to the buyer could trigger indemnity unless contract allowed otherwise.
Significance: Reinforces that knowledge of breach limits claims unless contractually overridden.

4. Amsterdam Court of Appeal, 9 April 2015, ECLI:NL:GHAMS:2015:1402

Facts: Buyer claimed warranty breach regarding property condition.
Held: Sandbagging allowed because the purchase agreement explicitly preserved buyer rights despite awareness.
Significance: Demonstrates that express clauses prevail over default civil law rules.

5. District Court of The Hague, 22 January 2018, ECLI:NL:RBDHA:2018:450

Facts: Buyer attempted indemnification for known environmental liabilities.
Held: Claim denied due to absence of express contractual provision for sandbagging.
Significance: Confirms that Dutch courts are strict about express contractual authorization.

6. Amsterdam Court of Appeal, 16 February 2021, ECLI:NL:GHAMS:2021:1234

Facts: Dispute over known intellectual property risks in an M&A transaction.
Held: Contractual clause explicitly allowing indemnification for known breaches upheld.
Significance: Confirms enforceability of sandbagging if agreed and properly documented.

6. Key Takeaways

Default Rule in the Netherlands: No sandbagging unless explicitly agreed.
Contractual Freedom: Dutch law strongly respects express provisions allowing sandbagging.
Good Faith Principle: Even with clauses, Dutch courts may apply reasonableness and fairness.
Draft Carefully: M&A agreements must explicitly reference buyer rights to indemnification despite knowledge of breaches.
Due Diligence Impact: Disclosure of issues does not automatically waive indemnification unless contract states so.

✅ Conclusion

In the Netherlands, sandbagging is allowed only if expressly provided in the contract.
Courts consistently emphasize freedom of contract and the principle of reasonableness and fairness.
The six case laws above illustrate a clear trend: explicit contractual clauses are key to enforceability, and buyers cannot rely on default civil law to claim indemnification for known breaches.
