The Committee existed from late 1904 until the formation of the AFIL in 1909, and succeeded in mediating in many disputes on estates in Cork city and county, as well as championing the cause of evicted tenants and agricultural labourers, who were (through the intense organisational work of Sheehan) becoming a considerable political presence in local and national politics in Cork. Meetings were held fortnightly in the City Hall, and were open to any UIL branch in Cork city and county willing and able to agitate for purchase of estates in their locality. Any body of tenants who were unable to reach a satisfactory settlement with their landlord were entitled to bring their case before the committee.
The political power of the committee was clear in the city by-election of June 1905 (caused by the death of sitting MP JFX O'Brien, and resulting in the election of former Lord Mayor Augustine Roche) and the general election of January 1906 (where no contest was held in any of the eight Cork constituencies, and by the fact that any addresses by O'Brien to committee meetings were the subject of much extensive reporting in the local and national newspapers, as they invariably touched on both local and (more often than not) national political issues.
The success of the Committee is hard to quantify, both there can be no doubt that it played a key role in the social and political life of Cork during the first decade of the twentieth century.
