which was the date determined by Congress after it passed and the president signed the Reapportionment Act of 1929. This resulted in the representation within the House to remain frozen for twenty years. Reapportionment of the House required Congress to pass a bill and the president to sign into law an act to reapportion the House from since the ratification of the constitution up until 1941, which is when a self-executing statute was enacted, thus making reapportionment an automatic process. Although the first sentence in this clause originally concerned apportionment of both House seats and taxes among the several states, the Fourteenth Amendment sentence that replaced it in 1868 mentioned only the apportionment of House seats. Even so, the constraint placed upon Congress's taxation power remained, as the restriction was reiterated in Article 1 Section 9 Clause 4. The amount of direct taxes that could be collected by the federal government from the people in any State would still be tied directly to that state's share of the national population. Due to this restriction, application of the income tax to income derived from real estate and specifically income in the form of dividends from personal property ownership such as stock shares was found to be unconstitutional because it was not apportioned among the states; that is to say, there was no guarantee that a State with 10% of the country's population paid 10% of those income taxes collected, because Congress had not fixed an amount of money to be raised and apportioned it between the States according to their respective shares of the national population. To permit the levying of such an income tax, Congress proposed and the states ratified the Sixteenth Amendment, which removed the restriction by specifically providing that Congress could levy a tax on income "from whatever source derived" without it being apportioned among the States or otherwise based on a State's share of the national population. Clause 4: Vacancies Generally states and territories fill vacancies within the House of Representatives according to their own laws, however when vacancies within the House exceed 100 members, the Speaker of the House will announce "extraordinary circumstances" have occurred, which obligates the executive authority of all states with vacancies to hold a special election within 49 days of the announcement. This election is initiated via a writ of election from the Governor (). Clause 5: Speaker and other officers; Impeachment
