TOKYO (AP) — The wife of former Nissan Chairman Carlos Ghosn is protesting restrictions on contacting her husband as he awaits trial in Japan on financial misconduct allegations, calling them a human rights violation.

Carole Ghosn said Tuesday the family’s fifth appeal to gain visitation rights was refused by a Tokyo court without explanation.

Prosecutors have said they sought the restrictions to prevent evidence tampering and collusion to create false narratives.

Ghosn, arrested in November, is out on bail. He says he is innocent.

Carole Ghosn said she has not been allowed to communicate with him for 124 days.

She said in a statement that “This cruel separation with no end in sight is further evidence of his persecution under Japan’s hostage justice system. It is a vicious retaliation designed to break him.”
