In the case of Gillis, Receiver v. California in 1934, the Supreme Court ruled on a dispute involving bankruptcy and state taxation laws. The plaintiff was a receiver for an insolvent corporation who sought to recover taxes paid under protest to the State of California. He argued that these payments were made during insolvency proceedings and thus should be considered as part of the bankrupt estate's assets rather than being used to pay off tax debts owed by the company prior to its insolvency. The court held that federal bankruptcy law did not prevent states from collecting taxes due before receivership began, even if those funds came out of what would otherwise be considered part of the bankrupt estate's assets. It reasoned that allowing such claims could potentially disrupt state revenue systems and undermine their ability to collect necessary funding for public services. This decision affirmed states' rights over their own taxation processes while also clarifying how federal bankruptcy laws interact with other areas of law at both state and national levels.

In the dissenting opinion for Gillis v. California, Justice Cardozo disagreed with the majority's decision to uphold a state law that allowed creditors to seize property from debtors who had declared bankruptcy before they received any discharge. He argued that this ruling violated the federal Bankruptcy Act, which was designed to give debtors a fresh start by discharging their debts and preventing further collection efforts. According to him, allowing states to bypass these protections undermined the uniformity of bankruptcy laws across all states as mandated by Congress in Article I Section 8 of Constitution. Furthermore, he contended that such practices could lead to unfair treatment of bankrupt individuals depending on where they lived or moved after declaring bankruptcy - an outcome contrary not only to principles of fairness but also potentially disruptive economically.
