In the case of Union Insulating & Construction Company v. United States, 1925, the Supreme Court ruled on a dispute involving tax law and bankruptcy proceedings. The Union Insulating & Construction Company had filed for bankruptcy and subsequently received an income tax refund from the government. However, this refund was claimed by both their trustee in bankruptcy and the U.S Government who argued that it should be applied to outstanding taxes owed by the company prior to its bankruptcy filing. The court held that under Section 234(a) of Revenue Act of 1918, which allowed refunds for overpayment of income taxes but did not specify how they were to be treated in cases where a taxpayer is bankrupt or insolvent; such refunds are assets belonging to estate in hands of receiver or trustee as per Bankruptcy Act §70a(5). Therefore, despite any claims made by creditors (including those with priority like IRS), these funds belong first and foremost to debtor's estate.

In the dissenting opinion for Union Insulating & Construction Company v. United States, the justice argued that the majority's interpretation of "labor" in Section 2(a) of the Lever Act was too broad. The justice believed that this section should only apply to manual laborers and not include administrative or executive employees as it would be unreasonable to assume Congress intended such a wide application without explicitly stating so. Furthermore, they contended that if Congress had meant to include all types of workers under this provision, they would have used more inclusive language like 'services' instead of 'labor'. They also pointed out inconsistencies in applying penalties based on whether an employee is considered part of ‘labor’ or ‘management’. Lastly, he disagreed with how broadly the court interpreted “necessaries” within wartime legislation context which could potentially cover any type of business transaction thus making almost every contract subject to government regulation during war times – a power he did not believe Congress intended to grant.
