In the 1916 case of Donohue v. Vosper et al., the US Supreme Court ruled on a dispute involving property rights and inheritance laws. The plaintiff, Mary A. Donohue, was contesting her late husband's will which had left his entire estate to his siblings (the defendants), rather than to her as per their prenuptial agreement. The lower courts in New York upheld the will, but Mrs. Donohue appealed to the Supreme Court arguing that she should have been entitled to at least one-third of her husband’s estate under New York law. The Supreme Court held that while it is true that a wife could not be deprived of certain statutory rights by any contract made before marriage unless expressly waived after marriage according to New York law; however, this rule does not apply when both parties are non-residents at time of execution and performance of such contracts even though they subsequently become residents thereof. Therefore, since Mr & Mrs Donahue were residents in Connecticut during their prenuptial agreement and only moved later into NY state where he died - leaving all his properties there for his siblings instead for Mrs.Donahue - hence court concluded that no violation occurred against NY state laws regarding spousal right over deceased spouse's properties.

The dissenting opinion in the Donohue v. Vosper case was not provided in the original document, making it impossible to summarize it. The Supreme Court's decision was unanimous with no recorded dissents.
