Dillon was knighted before or in 1639 and thus became Sir James Dillon. The same year he stood as MP, or "
knight of the shire" as county MPs were then still called, for
County Longford in the
Parliament of 1640–1649, the second of Charles I. Sir James was elected as one of the two members for County Longford on 28 February 1640. Parliament met on 16 March 1640. In its first session the parliament unanimously voted for four subsidies of £45,000 to raise an Irish army of 9,000 for use by the king against the Scots in the
Bishops' Wars. Dillon must have voted in favour. On 31 March 1640 Wentworth
prorogued parliament until the first week of June. On 3 April 1640, Strafford (i.e. Wentworth) left Ireland, called to England by the king to help him manage the Bishops war against the Scots. Strafford appointed
Christopher Wandesford as Lord Deputy to govern Ireland in his absence. Wandesford opened the second parliamentary session on 1 June 1640. News from England was the
Short Parliament had refused subsidies to the king. The Irish MPs regretted having agreed to subsidies and wanted to sabotage their own action by making the subsidies difficult to evaluate and to collect. After two weeks of inconclusive discussions, Wandesford prorogued parliament on 17 June. Parliament reconvened for the third session on 1 October. The House of Commons formed a committee for grievances that compiled a
remonstrance (complaint) against Strafford. The remonstrance was then approved by the House of Commons. Sir James must have voted against it in order to support Strafford. Wandesford prorogued parliament on 12 November, a day after Strafford's impeachment in Westminster by the
Long Parliament. Parliament met again on 26 January 1641. Lord Deputy Wandesford had died on 3 December 1640 and the Irish government had devolved to the
