"This time around Eddie Hearn and I had a meeting of minds very early on pre-contract. We were clear we wanted a minimum of a balanced panel. We jointly approached the British Boxing Board of Control and we're grateful to them because they've selected a balanced panel."
Quartarone, described as "competent" by Parker's matchmaker Stu Duncan, has controlled 91 fights, all in Europe, and several world title bouts, but this will be his biggest.
Scott, from Wellington, has judged 120 professional fights, including several of Parker's victories, the latest of which was his win over Carlos Takam in 2016, a unanimous points decision.
Parker has 18 knockouts in his 24 professional victories, while Englishman Joshua, who has won all of his 20 professional fights by stoppage, has never gone the distance.
Higgins added before leaving to join Parker in London: "All Joseph has to worry about is his training on the home straight and winning the fight and he's very good at compartmentalising. That's all he's concerned about and he trusts people around him to take care of the details."
Parker and trainer Kevin Barry arrived in London on Sunday and wasted no time getting into training after their flight from Las Vegas. That night they attended a boxing event in east London where Parker impressed many with his trim condition.
"We're feeling good," Higgins said. "I spoke to Eddie Hearn last night and he said 'gee, your man looks good and sharp, he's lost a bit of weight'.
"We discussed how some in England seem to be writing Joseph off but their side are clear that they know they're in a fight. They know we're here to win.
"Last time it was a very testing promotion, but do you know what, we got through it, we didn't take the referee thing lying down, Joseph won the fight, and the money is in the bank, so we're learning to manoeuvre through those situations.
"This time I'm happy to say it's a case of the opposite – promotionally it's been plain sailing.
"It's exciting times – it's the calm before the storm."
