Vallejos v Commissioner of Registration
On 30 September 2011, Justice Johnson Lam of the Court of First Instance of the High Court (CFI) ruled in Vallejos' case that existing legislation restricting FDHs from qualifying for permanent residence contravened the Hong Kong Basic Law. Lam also found that Vallejos and Domingo, but not the three other applicants, had fulfilled the condition of taking Hong Kong as their only permanent home and being ordinarily resident in Hong Kong for seven years. The Court of Appeal of the High Court overturned the CFI's decision on Vallejos' case on 28 March 2012. Vallejos and Domingo then jointly appealed to the Court of Final Appeal (CFA), which heard their case on 26–28 February 2013; the CFA rejected their appeal on 25 March 2013.
Quill Corp. v. North Dakota
South Dakota was the first state to complete its bill and establish the need for a Supreme Court judicial review. In October 2017, the state of South Dakota filed a petition for "certiorari" in the U.S. Supreme Court urging it to "abrogate "Quill"s sales-tax-only, physical-presence requirement". In the petition for "certiorari", under the case name "South Dakota v. Wayfair, Inc.", South Dakota noted that advances in computer technology have made it easier to determine appropriate sales tax based on the purchaser's location and requiring such "poses a minimal obstacle" in an era where retailers can easily tailor their online marketing based on customers' IP addresses. South Dakota argued that "Quill" should be overturned and that the case satisfied the Supreme Court's criteria for declining to overturn its previous ruling under the doctrine of "stare decisis". The Court agreed to hear the case in January 2018, with arguments heard in April 2018. The Court ruled in June 2018 on a 5-4 decision that the physical presence aspect of "Quill" was "unsound and incorrect" with the state of current technology, and overturned "Quill" along with the remaining parts of "National Bellas Hess".
