R v Latimer: R v Latimer [2001] 1 S.C.R. 3, was a decision by the Supreme Court of Canada in the controversial case of Robert Latimer, a Saskatchewan farmer convicted of murdering his disabled daughter Tracy Latimer.  The case had sparked an intense national debate as to the ethics of what was claimed as a mercy killing.  In its decision, the Supreme Court ruled that the crime could not be justified through the defence of necessity, and found that, despite the special circumstances of the case, the lengthy prison sentence given to Latimer was not cruel and unusual and therefore not a breach of section 12 of the Canadian Charter of Rights and Freedoms.  The Court also ruled that Latimer was not denied rights to jury nullification, as no such rights exist.  The prison sentence was thus upheld, although the Court specifically noted that the federal government had the power to pardon him.

The Supreme Court of the United States heard arguments in the appeal of the case March 1, 2010.  On June 24, 2010, the Supreme Court vacated part of Skilling's conviction and transferred the case back to the lower court for resentencing.  During April 2011, a three-judge 5th Circuit Court of Appeals panel ruled that the verdict would have been the same despite the legal issues being discussed, and Skilling's conviction was confirmed; however, the court ruled Skilling should be resentenced.  Skilling appealed this new decision to the Supreme Court, but the appeal was denied.  In 2013, the United States Department of Justice reached a deal with Skilling, which resulted in ten years being cut from his sentence.
