Toward the end of this opinion (in which the 9th Circuit forbids the City of Seattle from regulating the Olympic Pipeline), there’s an obscure but interesting holding which should be a note of caution to public owners transacting with federally regulated entities such as pipelines: executing a franchise agreement (and thereby agreeing to submit to safety measures & oversight in the agreement) does not constitute a waiver of the federally-regulated entity’s right to assert a preemption defense in the event the city seeks to enforce the agreement. The 9th Circuit reasoned that preemption is not a personal defense capable of waiver, but rather a power of the federal government.
This preemption twist needs to be kept in mind in planning major projects where federally-regulated entities are involved, as they can apparently seek to avoid certain contractually assumed liabilities or obligations under a preemption defense.
