The U.S. Supreme Court case Donaldson, Postmaster General v. Read Magazine, Inc., et al., 1947 revolved around the constitutionality of a statute that allowed the postmaster general to stop mail suspected of being part of a fraudulent scheme from reaching its intended recipient. The plaintiff, Read Magazine Inc., was accused by the postmaster general (Donaldson) of running a lottery scam and had their mail stopped as per this law. However, they argued that this violated their Fifth Amendment rights to due process because it did not provide them with an opportunity for judicial review before action was taken against them. In its decision, the Supreme Court sided with Donaldson and upheld the validity of the statute in question on grounds that it served public interest by protecting citizens from frauds conducted through mails while also providing sufficient safeguards for those accused under it - including notice about complaints received against them and opportunities to contest these accusations before any actions were taken based on them.

In the dissenting opinion for Donaldson v. Read Magazine, Inc., Justice Frankfurter argued that the majority's decision was a misinterpretation of Congress' intent in passing legislation to regulate mail fraud. He believed that Congress intended to protect citizens from fraudulent schemes, not restrict their access to legitimate business opportunities or information about them. The justice also expressed concern over the potential implications of this ruling on free speech and press rights, arguing that it could lead to government censorship under the guise of protecting against fraud. Furthermore, he contended that determining whether an advertisement is misleading should be left up to juries rather than postal authorities or courts because they are better equipped with common sense judgment needed for such decisions.
