Another member of Boston’s troubled Zoning Board of Appeal has resigned, news that came hours after Mayor Martin J. Walsh issued an executive order barring city employees from participating in marijuana companies that are seeking local approval from his administration.
The order — which also applies to immediate family members of municipal workers and officials, and promises sanctions against cannabis firms that include city employees — apparently prompted zoning board member Bruce Bickerstaff to step down. Walsh officials told the Globe Bickerstaff was in the process of finalizing his resignation letter.
Bickerstaff co-owns Silver Therapeutics, which is seeking city permits for a pot shop in Roslindale. City officials said there was no evidence he had acted inappropriately.
