Background
Bay Area Transportation Authority (BATA) and Grand Traverse and Leelanau Counties entered into an Interlocal Agreement resolving a dispute over the composition of BATA’s board. The agreement provided for seven directors, including county-appointed representatives, and stated that each county “shall appoint a County Commissioner” to serve as an ex-officio board member. It also contained an integration clause superseding prior negotiations, representations, proposals, agreements, and communications concerning its subject matter.
After Grand Traverse appointed two county commissioners to BATA’s board, BATA sued, alleging that the agreement permitted each county to appoint only one commissioner. During the litigation, BATA sought to introduce draft agreements and communications from the negotiations and to add Mattis D. Nordfjord, the counties’ negotiating attorney, as a witness. The circuit court excluded the negotiation evidence under the integration clause and barred Nordfjord because he was added late, Grand Traverse would purportedly be prejudiced, and his communications were protected by attorney-client privilege.
The Court’s Holding
The Michigan Court of Appeals affirmed the exclusion of evidence concerning prior negotiations and drafts. Because the Interlocal Agreement contained a valid integration clause and BATA did not allege fraud invalidating either that clause or the entire agreement, parol evidence could not be used to contradict the agreement’s terms or establish that the parties intended a different meaning.
The court reversed the ruling barring Nordfjord from the witness list. Although BATA’s amended witness lists were untimely, the record did not show that the late addition prejudiced Grand Traverse: Nordfjord was its own attorney, and the county had submitted his affidavit in support of summary disposition. Nordfjord may therefore be called, but he cannot offer inadmissible testimony about the negotiations and may invoke attorney-client privilege when applicable.
Key Takeaways
- A valid integration clause generally forecloses evidence of prior negotiations, drafts, and communications offered to contradict an agreement’s terms.
- When deciding whether to allow a late-added witness, the primary considerations are the moving party’s diligence and the prejudice that granting or denying the request would cause either side.
- A party ordinarily cannot establish prejudice from the late addition of its own attorney when it previously relied on that attorney’s affidavit, though evidentiary rules and attorney-client privilege still limit the testimony.
Why It Matters
The decision illustrates that an integration clause can sharply limit the evidence available in a contract-interpretation dispute even when the parties disagree about what the final language means. Prior drafts and negotiating history remain inadmissible unless the integration clause or the contract itself is successfully challenged on a recognized ground such as fraud.
It also confirms that untimeliness alone does not necessarily justify excluding a witness. Michigan trial courts must assess actual prejudice alongside diligence, particularly when the opposing party already knows the witness and has affirmatively relied on that person’s account during the litigation.
