In 1983, Toronto Police raided Morgentaler's newly opened clinic and he and his two colleagues were charged with providing illegal miscarriages. Once again Morgentaler used the defence of necessity and was acquitted by the jury. The Attorney General's office appealed the acquittal and the verdict was reversed by the Court of Appeal for Ontario, which substituted a conviction. Once again, an appeal court had overturned a jury acquittal. Before Morgentaler, this was unheard of. Once again, Morgentaler appealed to the Supreme Court of Canada. This time, Morgentaler challenged the law as unconstitutional on the grounds that it denied women the right to life, liberty, and security of the person.
