In February 2025, the sisters combined their votes to remove Chanin from the board of Chanat & Sons, which is the largest shareholder in Dusit Thani, and sought to reduce his influence within Dusit Thani.

At that time, Chanat & Sons held around 49.47% of Dusit Thani, totalling 422 million shares. Within the holding company, the report said the sisters’ combined voting power exceeded Chanin’s, with Chanin’s group holding 25.4%, Sinee’s group 26.57%, Sunong’s group 21.62%, and the estate of Thanpuying Chanat Piyaoui holding 24.99%.

Market attention also focused on Central Pattana Plc (CPN), the second-largest shareholder in Dusit Thani with a 17.09% stake, amid questions over its relationship with Chanin’s sisters and efforts to place representatives on Dusit Thani’s board.

The dispute spilled into Dusit Thani’s shareholder meetings. An extraordinary general meeting on September 26, 2025 included an agenda item to remove Chanin from Dusit Thani’s board. Although 42 shareholders — including Chanat & Sons — supported the removal, representing 79.61% of total shares, the bid failed.

Under Thailand’s Public Limited Companies Act, removing a director requires a vote of no less than three-quarters of shareholders attending and eligible to vote. At that meeting, 420 shareholders opposed the removal, accounting for 89.9565% of attendees, meaning the resolution did not pass. Other proposed items — including changes to the number of directors, appointments of new directors and changes to directors’ authority — were not voted on.
