Mirageas v. Massachusetts Bay Transp. Auth., 391 Mass. 815 (1984)

After a 13-year-old was run over by an MBTA trolley, the teenager’s foot was amputated. The jury verdict was affirmed on appeal, with the Massachusetts Supreme Judicial Court holding that the defendant waived its defense under G. L. c. 161A, §21, and that the damages awarded were not excessive.
