Inconsistency Resolution Clauses.
1. Meaning of Inconsistency Resolution Clauses
Inconsistency resolution clauses (also called conflict resolution or precedence clauses) are contractual provisions that determine which document, term, or agreement will prevail when there is a conflict or inconsistency between multiple documents or provisions.
Common in M&A agreements, licensing contracts, joint ventures, and multi-document arrangements.
Purpose: Avoid ambiguity, reduce litigation risk, and provide a clear hierarchy of authority among documents.
Typical language:
“In the event of any inconsistency between this agreement and any annex, schedule, or other document, the terms of this agreement shall prevail.”
2. Importance of Inconsistency Resolution Clauses

Reduces Disputes: Prevents litigation over conflicting terms.
Legal Certainty: Courts can enforce the intended hierarchy without guesswork.
Operational Efficiency: Guides interpretation during implementation.
Risk Mitigation: Critical in large, multi-document contracts like M&A or licensing deals.
3. Common Applications

Technology Licenses: Conflict between master license and addendums.
Corporate Governance: Hierarchy between charter, by-laws, and shareholder agreements.
Financial Agreements: Conflicts between term sheets, loan agreements, and guarantees.
4. Drafting Principles
Explicit Hierarchy: Clearly state which document prevails.
