16 plan. 285 U. S. 355, 361 (1932). Following the 15th decennial census in 1930, Minnesota lost one seat in its federal congressional delegation. The State’s legislature divided Minnesota’s then nine congressional districts in 1931 and sent its Act to the Governor for his approval. The Governor vetoed the plan pursuant to his authority under the State’s Constitution. But the Minnesota Secretary of State nevertheless began to implement the legislature’s map for upcoming elections.

Nowhere in the Federal Constitution could we find “provision of an attempt to endow the legislature of the State with power to enact laws in any manner other than that in which the constitution of the State has provided that laws shall be enacted.” Id., at 368.

Smiley relied on founding-era provisions, constitutional structure, and historical practice, each of which we found persuasive. Two States at the time of the founding provided a veto power, restrictions that were “well known.” Ibid. (citing provisions in Massachusetts and New York). Subjecting state legislatures to such a limitation “was no more incongruous with the grant of legislative authority to regulate congressional elections than the fact that the Congress in
