Over 10 years ago, Inco Ltd. was charged with allegedly discharging millions of untreated mine effluent into a creek near Levack Mine.
Inco was acquitted of those charges yesterday in Sudbury Court.
Ontario Court of Justice Guy Mahaffy said the provincial government didn't present enough evidence to convict Inco on the environmental charges from the 1994 incident.
Inco was originally charged with violating the Ontario Water Resources Act.
Inco allowed untreated effluent into Gassy Creek for eight straight days, between Feb. 23 to March 2, 1994.
During the first trial, Inco was convicted and fined $24,000. A second trial followed after a lengthy appeals process that went to the Supreme Court of Canada.
