Vallejos v Commissioner of Registration
Vallejos and Daniel Domingo appealed their cases to the Court of Final Appeal, and were respectively assigned the case numbers FACV 19 and 20/2012. They would be represented before the CFA by Michael Fordham; David Pannick continued to represent the Government. Chief Justice Geoffrey Ma rejected a further application for joinder by eight-year-old Liang Wing-ki, the Hong Kong-born daughter of mainland parents, whose next friend, mother Li Yinxian, filed suit on her behalf. Philip Dykes, for the applicant, argued that because Vallejos and Domingo's case would touch on issues of interpretation of the Basic Law under Article 158, Liang's interests would also be affected. In rejecting Liang's application, Ma stated: "We feel that the points you seem to argue are adequately covered and will be adequately covered". Liang and other Hong Kong-born children like her were ruled to be entitled to the right of abode in Hong Kong in the 2001 case "Director of Immigration v. Chong Fung Yuen".
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".
