Avinash Treebhoowoon - who was a hotel worker at the luxury Legends resort where Michaela was killed in January 2011 - claims he was tortured by police following his arrest.
The 32-year-old was acquitted of murder in July, along with Sandip Moneea.
His lawyer, Sanjeev Teeluckdharry, said: "This claim has been lodged because of all the prejudice, detention, torture and humiliation my client suffered."
Treebhoowoon said his wife suffered a miscarriage after he was arrested. He said his detention was arbitrary, illegal and that he was relentlessly tortured.
He also claims he has been shunned by society since the trial.
"It is difficult for him (to find a job)" said Mr Teeluckdharry. "He has been trying his luck everywhere but everybody knows about him. Even though his name has been cleared they are unwilling to take him into employment - especially tourist resorts."
Treebhoowoon and his co-accused were arrested the day after Michaela's body was found.
The 27-year-old from Co Tyrone, daughter of GAA boss Mickey Harte, had been on honeymoon on the island with her husband John McAreavey.
Her family announced last month that they are to sue a Mauritian newspaper which printed photographs of her dead body.
Mr Teeluckdharry said they should also launch legal proceedings against the Mauritian authorities.
He continued: "The McAreaveys should sue the Mauritian police and the State. The police have bungled the inquiry. Because of the police the national flag has been made to fly at half mast. The incompetence of the police has brought shame on the country."
