The Supreme Court ruled local governments can ban marijuana collectives through zoning laws.
The unanimous decision stemmed from a case in Riverside.
In November of 2011 the City of Redding passed an ordinance that said collectives could only have nine members or fewer, despite the ruling seven collectives stayed open and have welcomed thousands of patients.
On Monday, Redding's Assistant City Attorney, Barry DeWalt said the ruling makes it clear the city has the power to restrict the collectives.
DeWalt said he wasn't surprised by the ruling and said the seven collectives operating within city limits need to comply with city rules.
Jess Brewer, owner of Trusted Friends, a collective in Redding said his collective is his livelihood and what he believes in.
Brewer adding, "We're trying to give people safe access to medical marijuana and to be able to take care of their own needs."
However, DeWalt argued there's still plenty of opportunity for patients to legally obtain their medicine and said Redding is not trying to deny access to users.
DeWalt said the ball is now in the collectives court as to whether they decide to shut their doors or do otherwise.
Dewalt said he imagines the next step would be some sort of litigation between the collectives and the city.
