Automatic pistol-related charges laid against a national outlaw bikie gang figure after he was stopped in Albury were dropped on Monday in the wake of his execution-style killing.
The Norinco .45 calibre self-loading pistol was in the handbag of Shane Scott Bowden's then-girlfriend, Janet Campbell, along with other "items" linked to the pair.
Holbrook Highway Patrol officers pursued Bowden after he was detected hitting speeds of up to 182km/h on the Hume Highway near the Davey Road turn-off six years ago.
IN OTHER NEWS:
Aware of his criminal notoriety, Albury detectives attended the scene when Bowden's SUV was stopped just before the South Albury exit, shortly before midnight on January 2, 2015.
The pistol's magazine was loaded.
At the time, Bowden was the national sergeant-at-arms for the Mongols outlaw motorcycle gang.
But the charges - of possess an unregistered or prohibited firearm, possess a loaded firearm in a public place and possess ammunition without a permit - were never finalised.
That was until Tuesday, when Albury court registrar Wendy Howard marked the charges withdrawn and dismissed.
Police prosecutor Sergeant Andrew Coombs asked Ms Howard whether that was because Bowden had died.
"Yes," she replied.
Bowden, 48, having returned to the Finks outlaw motorcycle gang just three months earlier, was shot dead in his car soon after he drove his BMW into the garage of his Gold Coast home on October 11.
Suggestions have been made that Queensland bikies could be forced into secret crime and corruption commission hearings to uncover evidence about this and similar crimes.
