Constitutional Law

Overview

Tonkon Torp’s Constitutional Law practice is focused on helping businesses navigate complex constitutional challenges that impact their operations, regulatory compliance, and long-term strategy. Our attorneys bring deep experience in litigating constitutional matters across state and federal courts, with a particular emphasis on protecting commercial interests against overreaching regulation and unlawful governmental action.

We regularly represent companies in disputes involving constitutional principles that directly affect business activity. This includes challenges to state and local regulation under the Commerce Clause, defending against or pursuing claims under the Due Process and Takings Clauses, and addressing issues of federal preemption under the Supremacy Clause. We also advise and litigate on behalf of employers and contractors facing Equal Protection claims, as well as matters implicating the First, Fourth, Fifth, and Fourteenth Amendments when business rights and operations are at stake.

In addition to our core business representation, our attorneys dedicate time to pro bono constitutional and civil liberties work through partnerships with organizations such as the ACLU Foundation of Oregon and the CLiF Project. Tonkon Torp does not accept individual civil rights cases through direct inquiries. Our focus remains on advancing and defending the rights of businesses and institutions as they navigate the evolving landscape of constitutional law.
