37. Montana: Opening Marital Mail
Federal postal laws are incredibly strict regarding mail tampering, but this specific state law frames the federal crime as a highly specific domestic marital issue. An old statute dictates that it is considered a felony offense for a wife to open her husband’s mail without his explicit permission. The bizarre, highly specific phrasing of the law heavily reflects the unequal legal attitudes of the era it was written in. It highlights a historical period when financial independence, privacy, and property rights within a marriage were viewed through a highly restrictive, gendered lens that favored the male head of household.
