We can end the week with some good legal news in the fight against invasive species in the Great Lakes. A state appeals court in New York has rejected a challenge by shipping interests against the state’s ballast water regulations. The decision affirms the ruling of the lower court that the state may impose stricter requirements to protect the Great Lakes from ballast water pollution than the federal government’s minimal requirements. For more background on the case, see the previous guest post by Thom Cmar of NRDC, one of the lead attorneys on the case. Good work to the NY Attorney General’s office, NRDC, and NWF on this win.
