Can res judicata bar public highway claims after private easement litigation? Gillmor v. Family Link, LLC Explained

In Gillmor v. Family Link, LLC, the Utah Court of Appeals addressed whether res judicata can bar a public highway dedication claim when the same parties previously pursued private access rights over the same property. The court’s analysis provides important guidance on the scope of claim preclusion in property access disputes.

Background and Facts

Mrs. Gillmor engaged in three separate lawsuits seeking access to her property through defendants’ land. In 1984, her husband sued for a prescriptive easement, which settled with an easement agreement. In 2001, Mrs. Gillmor sued for declaration of her rights under that agreement. In 2007, she filed this suit claiming highway-by-public-use under Utah Code section 72-5-104. The district court dismissed the 2007 claims as barred by res judicata and imposed Rule 11 sanctions against plaintiff’s attorney.

Key Legal Issues

The central issue was whether Mrs. Gillmor’s public highway claim constituted the same claim as her previous private easement litigation under the claim preclusion branch of res judicata. The court also addressed whether Rule 11 sanctions were appropriate for filing claims allegedly barred by res judicata.

Court’s Analysis and Holding

The court applied the transactional theory of claim preclusion, focusing on whether claims arise from the same operative facts or transaction. All three suits shared an identical motivation: obtaining access to the Gillmor property over the Richards property. The court found that the public highway theory “could and should have been raised” in the prior suits, as it was legally and factually available but strategically omitted. The attorney’s speculation that pursuing both private and public claims simultaneously “would have been pretty dicey” supported this conclusion.

Practice Implications

This decision emphasizes that res judicata turns on the “essential similarity of the underlying events” and “common motivation” rather than specific legal theories. Practitioners pursuing property access rights should consider all available theories in initial litigation to avoid preclusion of alternative approaches. The court’s willingness to impose Rule 11 sanctions for filing claims barred by res judicata also highlights the importance of thorough legal research before pursuing successive lawsuits involving similar factual circumstances.
