Mark Kwaku Asiedu-Arthur Takes OSP to Court for Revoking His Appointment Without a Hearing

A former investigator with Ghana’s Office of the Special Prosecutor (OSP), Deputy Staff Officer (DSP) Mark Kwaku Asiedu-Arthur, has dragged the anti-corruption agency to the Human Rights Division of the High Court, alleging unlawful termination of his appointment.

Asiedu-Arthur, who previously served with the National Intelligence Bureau (NIB) until his dismissal in 2016, contends that his termination from the NIB was openly discussed during his OSP job interview in 2023—yet, in June 2025, the OSP withdrew his appointment on the same grounds, claiming it had only recently become aware of the prior dismissal.

In court documents filed by his lawyer Derrick Aboagye Asamoah, the applicant argues that the OSP violated his constitutional right to a fair hearing, per Article 23 of the 1992 Constitution, by failing to offer him the opportunity to respond before terminating his appointment.

“A public institution cannot rely on its own oversight as a reason to deny an individual employment or legal protection,” Asiedu-Arthur asserted in his affidavit.

■ Political Interference Claims

The former investigator further alleged that he faced victimisation at the OSP after leading a probe into the Scholarship Secretariat, which he claimed involved suspects close to Special Prosecutor Kissi Agyebeng, including former CEO Kingsley Agyemang, now a parliamentary candidate.

According to Asiedu-Arthur, the Special Prosecutor instructed him in October 2024 to halt the investigation into Agyemang “so as not to jeopardize his political ambitions.” After complying, he said he began facing retaliation despite having had his appointment confirmed in October 2024.

Mistaken Identity and Disputed Allegations

He also claimed a false petition was later submitted to the OSP, accusing him of holding another job under a different name—Michael Ebbah. The petitioner allegedly confused him with another individual, but the OSP reportedly acted on the complaint regardless.

Following this, Asiedu-Arthur said he was suspended without a hearing, and his appointment was eventually withdrawn based on the prior NIB termination—despite the fact that the OSP had previously acknowledged this during his hiring.

Reliefs Sought

He is now seeking:

▪︎ A declaration that the OSP’s actions were unconstitutional and procedurally unfair

▪︎ An order for reinstatement, or in the alternative, financial compensation for wrongful dismissal

▪︎ Damages for the violation of his right to administrative justice and the injury to his professional reputation

Asiedu-Arthur maintains that his removal was not only unjust and retaliatory but also a blow to the integrity of Ghana’s anti-corruption fight.

The Office of the Special Prosecutor has yet to respond publicly to the legal action.
