Eight Premier League clubs, including Chelsea and Manchester City, have blocked a proposed ban on same-party loans.
The rejection now allows teams to sign players from related clubs on loan during the January transfer window.
The proposed ban faced opposition from clubs that had affiliations or shared ownership structures.
Newcastle, now owned by the Saudi-led consortium, was among the clubs against the ban, as their majority owners, the Public Investment Fund (PIF), also own several clubs in the Saudi Pro League.
The vote required at least 14 out of the 20 Premier League clubs to pass the motion, but it fell short with only 12 clubs in favor of the ban.
The opposing clubs included Sheffield United, Manchester City, Chelsea, Everton, Wolverhampton Wanderers, Nottingham Forest, and Burnley.
The motion for the rule change emerged following the PIF’s acquisition of four Saudi teams during the summer, raising concerns about potential conflicts of interest and competitive balance.
