Bellingham Herald:  “A federal lawsuit is challenging Washington state’s authority to tax marijuana as long as marijuana remains illegal under federal law.  The case arises from the state’s attempt to collect sales taxes from a medical marijuana dispensary. But lawyer Douglas Hiatt, who filed it late Thursday, said it could throw a wrench in Washington’s plans for collecting taxes on recreational marijuana, too. . . . the dispensary’s operator, Martin Nickerson, who is simultaneously being prosecuted criminally for marijuana distribution and targeted by the state Department of Revenue for not collecting and remitting taxes on the pot he was allegedly distributing.”
