The sentencing hearing for Portland businessman Everton 'Beachy Stout' McDonald and Oscar Barnes has been pushed back to September 19.
The court was told that sentencing judge, Justice Chester Stamp, was not available.
The men were subsequently remanded.
A seven-member jury found McDonald and Barnes guilty of murder and conspiracy to commit murder on March 6 in relation to the businessman's wife, Tonia.
Tonia was killed on July 20, 2020, along the Sherwood Forest main road in Portland.
