Prosecutors on Sunday asked the police for more information in order to formally charge former president Maumoon Abdul Gayoom, chief justice Abdulla Saeed, top court judge Ali Hameed and chief judicial administrator Hassan Saeed.
Police had officially sought charges against the four who remain in custody accused of a plot to overthrow the government on February 28.
However, the reason behind the Prosecutor General's (PG) office's decision to send the case back to the police remains unclear.
Police had sought charges against Gayoom along with the two top court judges for attempting to destroy evidence believed to be in connection to the alleged coup plot.
The chief judicial administrator meanwhile, would face charges for refusing to come in for police questioning.
The island nation has been embroiled in fresh political turmoil after the Supreme Court on February 1 ordered the immediate release of jailed political leaders including self-exiled former president Mohamed Nasheed.
President Abdulla Yameen Abdul Gayoom on February 5 had declared a 15 day state of emergency after his last ditch attempt to convince the top court to revoke the order failed, purged the Supreme Court by arresting two judges and the remaining political leaders and ultimately had the order revoked.
As the state of emergency expired, president Yameen had got the parliament contentiously extend it by another 30 days.
Less than a day after the arrest of the two judges, the remaining three judges rescinded its ruling to release the political leaders referring to the concerns raised by president Yameen in the letters he had sent to the chief justice hours before state of emergency was declared.
The accusations against Gayoom included bribing lawmakers and judges to influence their authority while the deposed ruling party leader has also been accused of creating discord within the security forces to back the overthrow of his half-brother's government.
The two top court judges are accused of accepting bribes to influence Supreme Court rulings, abuse of power and blocking the functioning of the entire justice system.
In addition to Nasheed, the other top political leaders named in the now rescinded order included Jumhoory Party (JP) leader Gasim Ibrahim, religiously conservative Adhaalath Party (AP) leader Sheikh Imran Abdulla, former defence minister Mohamed Nazim, former vice president Ahmed Adheeb Abdul Ghafoor and Gayoom's lawmaker son Faris Maumoon.
Former prosecutor general Muhthaz Muhsin, magistrate Ahmed Nihan and Adheeb's uncle Hamid Ismail make up the rest of the list.
