On 27 March 1860 Pring was elected to the first Legislative Assembly of Queensland for the district of Eastern Downs, and served under Robert Herbert as Attorney-General in the first Ministry formed under responsible government from December 1859 to August 1865. In the second Herbert Ministry he filled the same office from July to August 1866. He was also Attorney-General in the Robert Mackenzie Ministry from August 1867 to November 1868; in the Charles Lilley Government from November 1869 to May 1870; and in the first Thomas McIlwraith Administration from May 1879 to June 1880, when he accepted a puisne judgeship of the Supreme Court of Queensland. Pring served as member of the Queensland Legislative Council from 24 April 1862 to 26 May 1863. He also served in the Assembly for Ipswich from 30 May 1863 to 4 August 1866; for Burnett from 22 April 1867 to 17 August 1870. He was elected in Town of Brisbane on 17 August 1870. He contributed to many acrimonious debates in 1871, which culminated in January 1871 in physical violence. On 10 January 1871, Pring repeatedly interrupted the member for Clermont, Oscar de Satge. Clark complained about Pring's "extremely offensive and personal remarks in regard to the Member for Clermont" and proceeded to make insulting remarks about Pring. Pring called on the Speaker to rebuke Clark, which he did. Pring then proposed that Clark exit parliament for five minutes to "settle all things", which the Speaker declared to be out of order. Pring responded by calling Clark "the dirty wretch". The Speaker told Pring not to continue this behaviour. Pring then threatened to kick Clark, by which time the Legislative Assembly was in an uproar with the Speaker unable to restore order. Clark and Pring continued to trade insults. Pring then rose as if to leave the Assembly, but, as he walked past Clark, he attacked Clark by grabbing his collar with one hand and tugged at Clark's beard with the other hand, yelling "Come outside and we will settle it". The Sergeant-at-Arms went to Pring saying "I take you in charge". Pring responded "Do you? You will have to catch me first!" and then raced out of the chamber, and the Sergeant-at-Arms was unable to catch him. The Speaker then issued a warrant for Pring's arrest for his contempt of Parliament 9, but did not sign it in order to allow Pring to end the matter by apologising, calling on Pring to attend the House on 16 January. However, Pring did not apologise but resigned the following day, evidently believing that would bring the matter to an end. However, on 22 January, the Speaker, in the absence of an apology from Pring, proceeded with the warrant and Pring was arrested in Dalby where Pring had gone on Court business. However, the police did not know what action to take after arresting Pring as he could not be delivered to the Parliament which was now in recess, so they ended up releasing him. Pring returned to Brisbane triumphant, where he addressed a crowd of sympathisers from the balcony of the Australian Hotel in Albert Street, promising that he would return to Parliament. He was elected in Carnarvon from 25 November 1873 to 2 January 1874. Following the retirement of Thomas Blacket Stephens due to illness, in May 1875 Pring stood for election for the South Brisbane seat in the Queensland Legislative Assembly, but was defeated by Richard Ash Kingsford. However, Pring was later elected in Brisbane City from 12 February 1878 to 15 November 1878 and for Fortitude Valley from 26 November 1878 to 28 May 1879. In 1863 Pring was offered the position of first Chief Justice of Queensland, over the head of the Judge Alfred Lutwyche, but declined the post, and Sir James Cockle was appointed.
Later life
Pring died at his residence in Brisbane on Thursday 26 March 1885, after a 14-month illness, of cardiac asthma. He was buried in Toowong Cemetery. He left his wife almost destitute.
