The Sports Authority of Thailand (SAT) has asked Gen Boonlert Kaewprasit when he will officially step down as the country's amateur boxing chief, according to media reports.
Gen Boonlert Kaewprasit greets the crowd at the Royal Turf Club last month.
SAT governor Kanokphand Chulakasem said he had formally asked Boonlert about his resignation as president of the Thailand Boxing Association (TBA), the country's governing body of amateur boxing, Manager Online reported.
Kanokphand said he had sent Boonlert a letter because the matter had become silent for a while.
Kanokphand's move came after Boonlert declared himself as leader of the anti-government Pitak Siam group.
Boonlert held a rally at the Royal Turf Club a few weeks ago and is organising another next Saturday at the Royal Plaza with the aim of overthrowing the government.
Kanokphand's deputy, Montree Chaiyaphan, said the SAT had not yet received Boonlert's resignation.
Montree said it was expected that Boonlert would step down in January and an election for a new TBA president must be held within 30 days of his resignation, Kom Chad Luek newspaper reported.
"We will not intervene in a sport association's internal matter," Montree said.
Boonlert said before the 2012 Olympics that he would step down as TBA chief if his boxers failed to win a gold medal in London.
As it turned out, Kaew Pongprayoon was Thailand's only boxing medallist, claiming a silver at the London Games.
It was the Thai boxing team's worst performance since boxer Somluck Kamsing won the country's first ever Olympic gold medal at the 1996 Games.
However, several Thai officials and fans complained that Kaew was robbed of victory against China's Zou Shiming in the 49kg final.
Boonlert did announce his resignation in London following Kaew's loss but has since said he would officially step down after he clears the association's debts.
Montree told Kom Chad Luek that the president of a sport association did not have to resign if his or her athletes were unsuccessful. But Boonlert has to because he promised to do so, Montree said.
The TBA was established last year after the International Boxing Association (Aiba) and the SAT revoked membership of the Amateur Boxing Association of Thailand (Abat) following a row between Abat bosses and Aiba president Wu Ching-kuo.
Boonlert was elected unopposed as the TBA's president. He and the TBA were promptly approved by Aiba.
