Hong Kong and Macau Affairs Office
From October 2019 to May 2020, while Kwok was Deputy Chairman of Legco's House Committee, no election for the vacant post of its Chairman took place, for which Kwok was accused by the Hong Kong and Macau Affairs Office and other pro-government voices of misconduct by paralysing Legco through filibustering tactics. In April 2020, pro-establishment lawmakers argued that Dennis Kwok was "no longer fit" to preside over sessions as his continued filibustering tactics had left multiple pieces of legislation in limbo.
