What Happened in Kahler v. Kansas?

SHERRY F. COLB

Cornell law professor Sherry F. Colb describes how the U.S. Supreme Court purported to allow the state of Kansas to substitute one insanity defense for another, but in fact approved its abolishment of the insanity defense altogether. Colb explains the difference between the insanity defense—an affirmative defense to the commission of a crime—and facts that negate mens rea—the mental element of a crime. Colb also notes how in dissent, Justice Stephen Breyer made a case for veganism, albeit probably inadvertently.

Michigan v. Vanderpool

Docket: 158486

Opinion Date: July 13, 2020

Judge: Michael F. Cavanagh

Areas of Law: Constitutional Law, Criminal Law

While conducting a probation compliance check on defendant John D. Vanderpool’s house, a probation agent found heroin. Defendant admitted that the heroin belonged to him. A few weeks later, defendant was arrested and was again found in possession of heroin. He was charged with two counts of possession with intent to deliver heroin and with violating probation. Defendant moved to suppress evidence from the compliance check, arguing that the search was illegal because he was not on probation at the time of the search, but the circuit court denied the motion. Defendant pleaded no contest to having violated probation and to having possessed less than 25 grams of a controlled substance, second offense. Defendant appealed, arguing that because he was not on probation when his home was searched, the search was unlawful. The Michigan Supreme Court agree: while the circuit court attempted to extend defendant’s probation before the compliance check, because the term of probation had already expired, the court did not have the authority to extend it. Consequently, the warrantless search of defendant’s home was not justified.
