New York’s Court of Appeals on Thursday ordered a new trial for Joel B. Steinberg on two civil causes of action brought against him by the biological mother of Lisa, the adopted 6-year-old girl he killed in 1987.

The state’s high court in a unanimous, unsigned ruling in Launders v. Steinberg, decided that two causes of action based on Steinberg’s alleged acts of abuse against the girl prior to the night of her death in November 1987 were improperly sustained in 1989 by then-Supreme Court Justice Eugene L. Nardelli of Manhattan, who now sits on the Appellate Division, 1st Department bench.
