The Public Service Commission of Indiana et al. v. Batesville Telephone Co., 1931, is a U.S Supreme Court case that revolved around the issue of rate regulation for public utilities by state commissions and its potential conflict with due process rights under the Fourteenth Amendment. The Batesville Telephone Company had been ordered by the Indiana Public Service Commission to reduce their rates, which they argued would not allow them to earn a fair return on their investment and thus violated their constitutional rights. The court ruled in favor of Batesville Telephone Co., stating that while states have power to regulate utility rates, such regulations must still respect companies' right to a reasonable return on investment as part of due process protections under the Constitution.

The dissenting opinion in the case of Public Service Commission of Indiana et al. v. Batesville Telephone Co., argued that the majority's decision to allow Batesville Telephone Company to increase its rates was incorrect and could potentially lead to unjust enrichment at the expense of consumers. The dissenters believed that there was insufficient evidence presented by Batesville Telephone Company proving their need for increased revenue, making it inappropriate for them to raise their rates without proper justification or approval from regulatory authorities like the Public Service Commission (PSC). They also expressed concern over how this ruling might set a dangerous precedent where other utility companies may feel emboldened to arbitrarily increase their prices without sufficient cause or oversight, thereby undermining consumer protections and fair business practices established by public service commissions across various states.
