In Canada the phrase was adopted in the case
Canada v Schmidt (1987) to determine whether
extradition would be a breach of
fundamental justice under the
Canadian Charter of Rights and Freedoms. A court may look at the justice system of another country, and disregarding "finicky" requirements of fundamental justice in Canada, may consider some potential punishments in other countries so outrageous that a person should not be put at risk by the extraditing government. The measure was used in
United States v Burns (2001) to find that the possibility of execution would shock the conscience. Critics such as Professor
Peter Hogg have suggested that the use of this measure indicates courts have "enormous discretion," and he argues this is demonstrated by inconsistencies between what is considered shocking and what is considered
cruel and unusual punishment. ==References==
