RE: Something's upmaystealer you ask: "Will the Tanzanian government back the Commissioner's decision?"
It is not a question of backing the Commissioner. It is a question of law. Is the PML and ML permits legal?
That will be decided in court . The Tanzanian Government has no authority under its constitutiion to overrule a law or statute.
The formal appeal to the Minister of Mines by Sonora is a courtesy act. The matter will be decided in court, unless the Commissioner corrects himself.
