Canadian Pacific Railway's attempt to block a lawsuit was denied by the Supreme Court. Residents of Minot, ND are filing the lawsuit against CP, whose train derailed in 2002 and released toxic anhydrous ammonia farm fertilizer into the air over the city. The toxic fumes killed one local man and caused damage to several other residents.
In 2006, a U.S district judge ruled that federal law protected CP from any claims that might arise from the derailment. However, the federal law changed the same year. Now, the Supreme Court has denied that CP is protected.
