Cynthia Coffman, the Colorado Attorney General, has asked the Supreme Court to reject a landmark lawsuit that has been filed by Oklahoma and Nebraska over the legalization of marijuana. In her brief, Coffman stated that Oklahoma and Nebraska “filed this case in an attempt to reach across their borders and selectively invalidate state laws with which they disagree.”

Nebraska and Oklahoma, on the other hand, believe that the legal pot market in Colorado has lead to a flood of ganja within their borders, and consider that a burden on their law enforcement and an infringement on their sovereignty. So they’re asking the Supreme Court to shut down Colorado’s dispensaries.

Coffman has also said that if the lawsuit was to be successful, then this would only make things worse in terms of the black market in the states.

If the stores did close, Colorado would be left with legalized marijuana use, but no way to regulate the supply. Coffman believes that this will bring in more cross-border traffic. The brief on Friday is the first time that officials in Colorado have had to make an argument in favor of the law.

The Supreme Court becomes the authority in a dispute between multiple states. Before the lawsuit gets a hearing, the high court must decide whether or not they want to take on the case, and this decision doesn’t have a timeline.

Coffman issued a statement on Friday that went on to say that even though she is a Republican that opposes the legalisztion of marijuana, she does share in the other states concerns about the trafficking that has come as a result of sales in Colorado.
