The lawyer acting for New Caledonian inmates says this week's court ruling to pay them compensation will result in more cases being filed.
Cecile Moresco says a further 60 cases will be submitted in the coming weeks after a Noumea court ordered the French state to compensate 30 inmates for locking them up in conditions devoid of human dignity.
Mrs Moresco says she hopes things will now be moving more quickly.
The compensation ruling obliges the state to give to each of the inmates 200 US dollars plus compensation of between 1,000 and 7,000 dollars depending on the length of their incarceration.
The ruling follows a complaint by about 100 prisoners whose case was lodged with the help of the International Observatory of Prisons and the territory's Human Rights League.
Noumea's Camp Est jail was built in the 19th century and suffers from some of the most serious overcrowding of any French-run detention centre.
