The Pakistan Cricket Board (PCB) told Afridi to appear before a three-man disciplinary committee after the former one-day captain abruptly decided to retire from international cricket last week.
"The process followed by the PCB does not conform to the law as even under Pakistan s constitution there is a right given to everyone to be heard before a case is decided," Afridi s lawyer Syed Ali Zafar told a news conference.
The PCB said Afridi violated the players code of conduct in announcing his retirement and suspended his central contract and revoked all no-objection certificates (NOCs) that would have allowed him to play abroad.
The move prevents him from playing for Hampshire in the Twenty20 league in England and in next month s Sri Lankan Premier League.
Afridi had developed differences with coach Waqar Younis over selection matters during last month s tour of the West Indies and his public criticism saw the PCB replace him as captain.
The star also levelled serious allegations of mistreatment against the PCB, saying he would not play under the current board set-up, headed by Ijaz Butt.
When asked if Afridi might take legal action should the PCB committee take action in his absence, Zafar said: "all the options are open. We will knock (on) the door of justice and that we have repeated all through this case."
