LANSING, Mich. — After hearing arguments, the Michigan Supreme Court has dropped a case that involved the death of a 45-year-old woman with asthma and the work of Lansing paramedics.

The decision means there’s no liability for the Lansing fire department and paramedics. Tracy McLain’s husband insists she suffered irreversible brain damage and died in 2009 after a breathing tube was mistakenly placed in her esophagus instead of her trachea. Lawyers for Lansing dispute that the tube was in the wrong place.

The Michigan appeals court said immunity applied because there wasn’t evidence of “gross negligence or willful misconduct.” The Supreme Court last week said it won’t upset that decision.
