Boxing will only be included in the programme for the 2028 Olympics in Los Angeles if the International Olympic Committee (IOC) has found an international federation partner by early next year.
The IOC said in a statement on Wednesday that "for governance reasons" it was not able to organize a third Olympic boxing tournament, following 2021 in Tokyo and this summer's Paris Games.
The IOC stepped in to keep boxing in the Games after it first suspended and last year de-recognized the International Boxing Association (IBA) in connection with long standing IBA governance and financing concerns.
Wednesday's statement came in response to a Court of Arbitration for Sport (CAS) ruling in which the world's highest sports court dismissed an IBA appeal.
The CAS said on Tuesday it upheld the IOC decision from 2023 because IBA “had not complied with the conditions set down by the IOC for recognition.”
The IOC welcomed the CAS decision and said boxing remained on the 2021 and 2024 programme in order "to protect the sport of boxing and the athletes," and that it wants to continue with the sport "because of the universality and high social inclusivity of boxing."
However, it said it was now up to national boxing federations and national Olympic committees to find a suitable partner which can be recognized by the IOC as an international federation - with conditions including good governance, the integrity of competitions, transparency of finances and accounts, and autonomy.
"The NOCs and National Boxing Federations hold the future of Olympic boxing in their own hands, and the required actions cannot be clearer," the IOC said.
"At the moment, boxing is not on the sports programme for the Olympic Games LA28. In order to remedy this, the IOC needs to have a partner International Federation for boxing by early 2025."
A new organization, World Boxing, was founded in 2023 with the aim of ensuring that "boxing remains at the heart of the Olympic movement." It had 27 members for its inaugural congress in November, including the United States, Britain, Germany, Brazil and Australia.
The IBA meanwhile voiced disappointment after the CAS decision which came after a hearing of all parties in November.
It accused the CAS of bias and said it was "far from independent" of the IOC and did not take its wide-ranging reform efforts into account.
IOC president Thomas Bach was accused by IBA to be "driven by personal and purely political reasons" through which he "disrespected the Olympic Charter and discredited himself and the IOC as an organization naming the reason behind IBA’s recognition withdrawal."
The statement added that IBA would decide on another appeal at the Swiss Federal Tribunal after its legal team has studied the full CAS verdict.
Should the IBA decide to appeal it will face a difficult case because under Swiss law the tribunal will only act if procedural requirements are not fulfilled or the CAS ruling breached national law.
