DEPARTMENT OF COMMERCE v. MONTANA

Opinion of the Court

In 1832, Congress considered, but did not adopt, a proposal sponsored by John Quincy Adams that was the exact opposite of the Jefferson method. Instead of disregarding fractional remainders, Adams would have treated every fraction as a unit. Thus, using the former example as a hypothetical, both Connecticut and Rhode Island would have received one more Representative under the Adams method than they actually received under the Jefferson method. The Adams method is sometimes described as the "method of smallest divisors" and is said to favor the smaller States.20 It has

never been endorsed by Congress.

In 1842, Congress abandoned the Jefferson method in favor of an approach supported by Senator Daniel Webster. The Webster method took account of fractional remainders that were greater than one-half by allocating "one additional representative for each State having a fraction greater than one moiety." 21 Thus, if that method had been used in 1790, Connecticut's quota of 7.89 would have entitled it to 8 Representatives, whereas Rhode Island, with a quota of 2.28,

The third apportionment established a ratio of 35,000, which provided a House of 181 Members. Act of Dec. 21, 1811, 2 Stat. 669. The 1822 apportionment Act increased the ratio to 40,000 and the size of the House to 213. Act of Mar. 7, 1822, 3 Stat. 651. The 1832 apportionment Act provided for 240 districts representing an average of 47,700 persons each. Act of May 22, 1832, ch. 91, 4 Stat. 516. See generally L. Schmeckebier, Congressional Apportionment 111-113 (1941).
