Summary
Background
The dispute was between the State of Missouri, acting through the St. Louis circuit attorney, and Mallinckrodt Chemical Works, a Missouri chemical company. In 1910 the Secretary of State sent the company a letter and a statutory form asking for a sworn affidavit that it had not joined any pools, trusts, or similar combinations. The company willfully refused to file the affidavit, and Missouri prosecuted to forfeit the company’s charter. The Missouri Supreme Court affirmed forfeiture, and the case reached the United States Supreme Court.
Reasoning
The main question was whether Missouri’s statute and its prescribed affidavit violated the Constitution by denying due process or equal protection. The Court said the affidavit must be read with other state anti‑trust provisions and that the disputed term “trust certificates” is understood in that statutory context. The Court rejected complaints about the form, venue language, and date blanks as insubstantial. It also held that treating corporations differently from individuals for this disclosure requirement was reasonable because corporations are created by the State and act through agents, so their affiliations are harder to trace. For those reasons, the Court upheld the statute and affirmed the forfeiture judgment.
Real world impact
The decision confirms that Missouri can require annual sworn disclosures from corporations about anti‑trust participation and punish willful noncompliance by forfeiting corporate charters or imposing fines. Corporate defendants who refuse the demanded disclosure face loss of charter or other penalties under the statute.
