The Blackstone Headwaters Coalition, Inc. v. Gallo Builders, Inc., RH Gallo Builders, Inc., Arboretum Village, LLC, Steven A. Gallo, and Robert H. Gallo

Blackstone Headwaters Coalition · United States District Court for the District of Massachusetts · November 30, 2025 · No. 4:16-cv-40053-MRG

Summary

The United States District Court for the District of Massachusetts explains its reasons for granting the plaintiff's motion in limine to exclude a letter from the U.S. Army Corps of Engineers. The court concludes that the defendants failed to establish the letter's relevance, that its admission could mislead and unfairly prejudice the jury, and that the letter was untimely disclosed. The court also rejects the defendants' arguments that the letter was entitled to Skidmore deference or that the Army Corps had the final word on whether the disputed waters constituted Waters of the United States under the Clean Water Act.

Holdings

  1. The defendants failed to establish that the letter was relevant under Federal Rule of Evidence 401 because they did not provide the complete underlying application or sufficient information to determine the basis and significance of the Corps's determination.
  2. Even if the letter had some relevance, presenting it on agency letterhead without the underlying context would create a risk of misleading the jury and causing unfair prejudice, warranting exclusion under Rule 403.
  3. Federal Rule of Civil Procedure 26(e) does not authorize the production of materially new evidence on the eve of trial when the opposing party lacks sufficient time to investigate and conduct discovery concerning that evidence.
  4. The Army Corps of Engineers does not have the final word on whether a discharge violates the Clean Water Act in a citizen suit; the ultimate decision rests with the court.
  5. The letter was not entitled to persuasive weight under Skidmore because it lacked thorough reasoning and documentary support independent of the defendants' representations.

Questions Presented

  1. Whether the Army Corps of Engineers letter was sufficiently relevant under Federal Rule of Evidence 401 to be admitted.
  2. Whether admitting the letter without its underlying application or supporting context would create a risk of misleading the jury or unfair prejudice under Federal Rule of Evidence 403.
  3. Whether the defendants' late disclosure of the letter complied with Federal Rule of Civil Procedure 26(e).
  4. Whether an Army Corps of Engineers determination concerning Waters of the United States is entitled to Skidmore deference and is dispositive in a Clean Water Act citizen suit.
