Tribes: Flawed Line 5 Review Tramples Treaty Rights

For Michigan's tribal nations, the Straits of Mackinac are not merely a shipping lane or a scenic crossing — they are the heart of a treaty-protected fishery that has sustained Indigenous communities for generations. That is why the latest federal review of Enbridge's Line 5 pipeline has drawn sharp condemnation from tribal leaders, who argue the process was engineered to reach a predetermined conclusion while sidelining the very rights the United States promised to protect in perpetuity.

The tribes' central complaint is that the federal review treats treaty rights as an afterthought rather than a binding constraint. In their view, the analysis fails to grapple with how a catastrophic rupture in the Straits would not just pollute water but would destroy the fish populations that tribal members rely on for subsistence, ceremony, and commerce. By framing the pipeline's risks in narrow, technical terms — flow rates, corrosion models, spill response times — the review sidesteps the deeper question of whether the project can coexist with the sovereign obligations the federal government owes to the tribes.

A Pattern of Procedural Shortcuts

This is not the first time tribal nations have watched federal agencies move the goalposts on Line 5. Previous reviews have been paused, restarted, or narrowed in ways that consistently benefit the pipeline's operator. The current iteration, tribal advocates argue, continues that pattern: it narrows the scope of environmental analysis, limits public comment windows, and treats tribal input as a box to be checked rather than a substantive voice in the decision. The result, they say, is a review that is legally defensible on paper but fundamentally illegitimate in practice.

The stakes extend beyond the pipeline itself. If the federal government can greenlight a project that threatens treaty resources through a process that marginalizes tribal consultation, it sets a dangerous precedent for every future infrastructure decision touching Indigenous lands and waters. Tribal leaders are signaling they will not accept that outcome quietly, and legal challenges are widely expected regardless of the review's final conclusion.

For Michigan residents, the dispute is a reminder that Line 5 is not just an energy debate — it is a test of whether the state and federal governments can honor the oldest promises in their legal history. The tribes are not asking for special treatment; they are asking for the review to actually reckon with what is at stake. Until it does, the conflict over Line 5 will remain unresolved, and the Straits will remain a flashpoint where treaty rights and industrial ambition collide.
