On July 22 K2 Promotions filed for a permission, which the WBA reviewed, and they came to the following conclusion:
The determining factor was a boxer with such devastating punching power as Golovkin, entering a world title fight against a career-long welterweight.WBA said:
The Championships Committee and the Presidency have not agreed to sanction this bout as a title fight because Brook has never fought as a middleweight," said WBA president Gilberto Jesus Mendoza at the time of the announcement in July. "The intent of the organization is to try to protect the integrity and health of the fighters.
We do not oppose the fight, per se. But the rules of the organization stipulate that Golovkin and/or his representatives must request special permission in advance to fight Brook. Under the circumstances, if Golovkin were to lose to Kell Brook, the title would become vacant and would not end up in the hands of the British pugilist.
In addition the WBA has ruled that Golovkin and Jacobs will be ordered to enter negotiations for a mandatory title fight if they both win their next bouts (Jacobs is rematching Mora)
