[1] The United Kingdom and countries whose legal system is based on common law, such as Canada, India, Israel, and Ireland, have similar legal frameworks of reserved powers.
[2][failed verification] In Australia, despite the centralized nature of the constitution, the High Court adopted the "reserved powers doctrine" which was used until 1920 to preserve as much autonomy for the states as can be interpreted from the constitution.
This practice changed with the Engineers' Case which led reserved powers to be given to the Commonwealth.
[4][5] This amendment does not refer to powers “explicitly” or “expressly” granted to the federal government, and therefore the federal government possesses many implied powers that are not reserved to the states.
[7] The Supreme Court continues to occasionally decide cases striking down federal laws that exceed both the explicit and implied powers of Congress, as in Murphy v. National Collegiate Athletic Association (2018).
