It's good news because this action will hopefully take the decision to ban these animals out of the hands of the politicians where there is no procedure for public comment, scientific debate, rebuttal of risk assessment, analysis of economic impacts, or any of the other rules required by the official listing process and gives the United States Fish and Wildlife service the authority to follow the regulatory process.
The regulatory process in place for lacey act listing will give stakeholders an opportunity for serious discussion and scientific debate as well as the ability to offer alternatives to an outright ban.
To put it simply, Politicians deciding our future is bad ... USFWS conducting a process designed to equally consider all factors and incorporate external input is good.
Hope this helps.
