In the case of Walling, Wage and Hour Administrator v. Halliburton Oil Well Cementing Co., 1946, the U.S Supreme Court ruled in favor of Walling. The central issue was whether workers who were involved in oil well cementing and servicing should be paid overtime under the Fair Labor Standards Act (FLSA). Halliburton argued that these employees were exempt from FLSA provisions because they were engaged in interstate commerce. However, the court disagreed with this argument stating that while their work was indirectly related to interstate commerce, it did not qualify them for exemption as per Section 13(a)(1) of FLSA which applies only to those directly participating in such activities. Therefore, these workers were entitled to receive overtime pay according to federal law.

In the dissenting opinion for Walling v. Halliburton Oil Well Cementing Co., Justice Frankfurter argued that the majority's interpretation of the Fair Labor Standards Act was too broad and failed to consider Congress' intent when drafting it. He contended that Congress intended to exclude employees engaged in interstate commerce from overtime pay requirements, not just those directly involved in production for such commerce. The majority's decision, he believed, would lead to an unwarranted expansion of federal power over local activities and could potentially disrupt state labor laws and practices. Furthermore, he criticized the Court for failing to provide clear guidance on what constitutes "engaged in commerce" under the Act, leading to uncertainty and potential litigation for employers.
