In November 1641 was appointed anew by king and parliament to be judge "ad vitam aut culpam".
[1] His rise and influence in the Scottish government was recognized on 20 December 1646, when he was created "Lord Falconer of Halkerton", with destination to himself and his heirs-male whatsoever.
On 15 February 1649 he was deprived of his seat in the College of Justice, and "ordained to lend money for the public use", on account of his accession to the "engagement".
He appears, however, as Baron Falconer in the list of Scots nobility in 1650, and was a commissioner of supply for Kincardineshire in 1656 and 1659.
