Descended from a wealthy Dublin trading family, Lawless was the second son of Valentine Browne Lawless, 2nd baron Cloncurry, whose father had purchased estates in counties Kildare, Meath, Dublin and Limerick.
Although his father withdrew from politics after the death of his wife in 1841, Lawless, as the son of ‘Ireland’s patriot peer’, was spoken of as a future repeal candidate for Kildare in 1844.
As the agricultural crisis in Ireland worsened, Lawless’s faith in the Whigs quickly evaporated. In December 1846 he argued for a ban on food exports from Ireland, the suspension of distillation from grain, ‘to prevent the converting of vast quantities of the people’s food into poison’, and the opening of the country’s ports to foreign provisions. His first contribution to parliamentary debate came in February 1847 when he criticised the Whigs for their tardiness in taking effective action to deal with the famine.
Described as having ‘a head that runs out behind like the point of a sugar loaf, hence a much receding forehead’, Lawless was regarded as a ‘pleasing speaker’ and a ‘consistent and useful’ member.
Lawless consistently supported William Sharman Crawford’s tenant-right proposals, voting for his Irish landed property bill in 1847, and attending the Tipperary meeting of the Tenant League, 16 Oct. 1850.
An active reformer, Lawless supported free trade, the ballot, and the removal of duties on newspapers and Jewish disabilities in 1852-3, but was absent from the division on Palmerston’s amendment to the local militia bill, which brought down the Russell ministry, 20 Feb. 1852. He soon expressed disappointment in Lord Derby’s ministry, arguing that the good intentions expressed by the Irish viceroy Lord Eglington were never likely to be acted upon. He strenuously opposed the Conservatives’ plan to introduce a coercion bill unaccompanied by remedial measures.
Having defended John Sadleir and William Keogh for accepting office in the Aberdeen ministry in January 1853, he voted for Gladstone’s budget, 2 May 1853.
On the question of education, Lawless, like his father, actively supported the national system and encouraged the establishment of agricultural schools. With regard to the Queen’s Colleges, he lamented the ‘misunderstanding’ between the government and the Catholic hierarchy, which made it unlikely that they would ‘be of the use he had hoped they would be’.
