VANCOUVER – A Federal Court judge has reserved a decision on expanding the criteria for who can currently grow their own medical marijuana.

Lawyer John Conroy appeared in Vancouver court on Friday to ask Judge Michael Phelan to vary a ruling he made in February that struck down legislation requiring patients to buy medical marijuana from designated growers.

Phelan gave the Liberal government six months to come up with a new law and extended an injunction allowing 28,000 medical patients to continue growing or possessing cannabis.

But Conroy, who represented four British Columbia plaintiffs argues the ruling "overlooked or accidentally omitted" certain issues, and says the injunction should be expanded to include other patients who previously held permits to grow medical marijuana.

He also asked the judge to allow licence-holders the right to change the address on their licence, and he wants the judge to clarify that a 150-gram possession limit does not apply to marijuana stored by patients who grow their own pot or get it from designated growers.

Conroy says he expects Phelan to release a decision on the motion to reconsider soon because the new legislation is due by the end of August.
