Will, you are correct that ultimately, it's granting Constitutional commerce clause protections to corporations is what allows the coal train to come through Seattle despite community wishes.
I103 would authorize the city council to protect our community with Rights for Nature; and corporations that attempt to challenge these regulations would not have personhood rights or constitutional protections, such as the commerce clause. If the city does not step up to protect our community, i103 allows for any citizen to have standing to do so. I103 also includes a formal call to state and federal officials to change laws that currently allow corporations to overturn the health, safety and wellbeing of communities nationwide.
Also, see Section 5d of i103 for the exact text below:
(d) Corporate Constitutional Powers. Corporations in violation of the rights and prohibitions established by this ordinance, or seeking to engage in activities prohibited by this ordinance, shall not have the rights of “persons” afforded by the United States or State Constitution, nor shall those Corporations be afforded rights under the First or Fifth Amendments to the United States Constitution or corresponding sections of the State Constitution.
(e) Corporate Preemption Powers.
(1) Corporations in violation of the rights or prohibitions established by this ordinance, or seeking to engage in activities prohibited by this ordinance, shall not possess the authority or power to enforce State or federal preemptive law against the people of this municipality, or to challenge or overturn municipal ordinances adopted by this municipality, when that enforcement or challenge interferes with the rights asserted by this ordinance, or interferes with the authority of the municipality to protect the health, safety, and welfare of its residents.
(2) No permit, license, privilege or charter issued by any State or federal agency, Commission or local government to any person or any Corporation operating under a State charter, or any director, officer, owner, manager or agent of a Corporation operating under a State charter, which would violate the prohibitions of this ordinance or deprive any municipal residents of any rights, privileges, or immunities secured by this ordinance, the State Constitution, the United States Constitution, or other laws, shall be deemed valid within this municipality.
