The Magpies, who face a similar complaint from French club Sochaux, are alleged to have tapped up the League One side’s goalkeeper and have been reported by the chairmanNewcastle United have been formally reported to the Football League by Charlton Athletic after they spoke to goalkeeper Rob Elliot without permission.
The Addicks have complained that the Magpies have breached Premier League Regulations Section K3, 8 and 9 and Football League Regulation 7.62.
Charlton chairman Michael Slater is adamant that his complaint will be upheld as the evidence against Newcastle is believed to be damning.
He told the club's official website: "It is well known that Rob is in the last year of his contract, but this does not mean that clubs are entitled to approach and speak to him without our authority.
"At no time did we give Newcastle permission to speak to Rob.
"Having considered the evidence we have received, we are confident that once the governing body investigates the matter, it will conclude that approaches have been made directly and indirectly to Rob and our complaint will be upheld."
Newcastle have already been fined £30,000 for failing to control their players in an on-field bust-up against Arsenal which saw midfielder Joey Barton slapped in the face by Gervinho, who was sent off for the incident.
They have also been reported to Fifa by French club Sochaux for a similar complaint to which Charlton are taking action against, after Modibo Maiga refused to play in light of the Magpies' interest.
Slater added: "We intend to work closely with Sochaux in order to ensure that all facts regarding Newcastle's actions are thoroughly investigated."
