Law & Order: Special Victims Unit: Season 5, Episode 24

Poison

A 4-year-old girl passes out and is hospitalized after having a huge amount of detergent in her stomach. Her 7-year-old sister reveals their mother (Cynthia Gibb) forced the child to drink it, but a judge (Tom Skerritt) disqualifies the sister's testimony. Novak and Clark (Marlo Thomas) investigate the judge due to his prior mishandling of an earlier child abuse case, in which he falsely jailed a woman (Lecy Goranson).
