Mauritian authorities have been handed a March 1 deadline to prosecute a security guard suspected of conspiring to burgle the school teacher's hotel room.
Dassen Narayanen will see all charges against him dropped if the Director of Public Prosecutions (DPP) fails to lodge a formal charge by the imposed date.
The 27-year-old is the only person facing charges arising from the previous police investigation which culminated in two hotel workers being acquitted of Michaela's murder.
Narayanen is accused of conspiracy to commit larceny at the Legends Hotel on January 10, 2011. But lawyers for the man have consistently argued that he is facing an "impossible offence" as he was charged along with Sandip Moonea -- one of the hotel officials who was cleared of the murder.
The District Court in Mapou has given authorities the deadline.
