Attempts by officials to survey land in Pallimunai, Mannar were halted on Tuesday after villagers protested against further land grabs and refused entry to the officials.
The land which originally belonged to 19 Tamil families is currently under the the military's control and houses a navy base.
The families said they had lived in the 25 house site in question since 1956, but were displaced in 1990 due to the conflict.
On February 2nd, 2013 a case was filed in court by the land owners. A further hearing is scheduled for next month.
