Nancy Kissel, jailed for life early this month for the murder of her wealthy banker husband, yesterday lodged an appeal against the High Court ruling. It is understood the grounds of the appeal are extensive, encompassing a number of the rulings during the course of the three-month trial. It will also challenge the summing up of the evidence and the directions given to the jury by the trial's judge, Mr Justice Michael Lunn. The High Court confirmed that the papers were yesterday filed by the firm of Kissel's solicitor, Mallesons Stephen Jaques, but there were no further details. The prosecution said Kissel, 41, drugged Robert Peter Kissel, a senior Merrill Lynch banker, with a sedatives-laced milkshake before bludgeoning him with a heavy metal ornament in their luxury Parkview flat in November 2, 2003. His body was found rolled up in an old carpet in a storeroom in the Tai Tam complex. Michigan-born Kissel admitted killing her husband but argued she acted in self-defence after he threatened to kill her and take away their three children. A jury of seven unanimously found her guilty of murder on September 1. Mr Justice Lunn sentenced her to life, as required by law. Kissel is now imprisoned in the Tai Lam Centre for Women in Tuen Mun. The hearing of the appeal is expected to begin in about nine months at the Court of Appeal. Meanwhile, the custody hearing over the three Kissel children between Jane Clayton, the victim's sister, and Hayley Kissel, his sister-in-law, will begin later this week in New York City. The children, who are under temporary custody of Hayley Kissel, will inherit up to US$18 million from their father's estate.
