Only one class of new rights was created by the act of 1832. This was the £10 occupation qualification. According to the act, the franchise was granted to all male persons who for a year before registration had occupied as owner or tenants "any house, warehouse, country house, shop or other building, either separately or jointly with any land" of a clear yearly value of £10. The land must be within the electoral limits of the borough; and in order to qualify, the occupier must have been rated in respect of such premises, to all rates for the relief of the poor; and he must have paid at the time of registration all rates and taxes due from him the preceding April.

This occupation franchise was the characteristic of the borough franchise after 1832. As ownership furnished the ordinary qualification for franchise in the counties, so in the boroughs, occupation, actual or constructive, was the basis of the suffrage. While however, in the counties no provision was made for ascertaining the true value or bona fide rent which was to qualify for the franchise; in the boroughs, assessment to the taxes was embodied with the condition of value, and actual payment was super-added. There was another difference between the character of the county and borough franchises, as determined by the Reform Act. In the latter no claimant could be registered as a voter if he had received parochial relief within the past twelve months; in the counties, no disqualification was attached to the receipt of poor-relief. ...

The Liberals of Birmingham realized that if they were to retain the third seat, their vote must be divided economically between the three candidates.
To prevent waste of votes, an organization must be built up which could control absolutely the choice of the elector; and each elector must vote invariably as he was told. The success of the Birmingham organization, which soon became known as the Caucus was unbroken and no Conservative candidate was returned. It was copied in many other constituencies and inaugurated a new era in the development of party electoral machinery, the effect of which upon the representative system has been profound.
