"We thank God. Our prayers for justice have been heard," the girl's father said from Idukki district.
Her mother said she and her husband were grateful to all those who helped them in their prolonged pursuit of justice.
CPI(M) veteran and former chief minister V S Achuthanandan, who has taken the initiative in helping the parents of the girl to pursue the case, said he was happy that justice had been delivered though it came a bit delayed.
In a statement here, the 88-year-old leader said he would continue his struggle for justice to victims in similar cases.
P K Sreemathy, leader of CPI-M's women wing AIDWA and a former minister, said the apex court verdict in the Suryanelli case could be considered as a landmark order to be followed by courts in trial of sexual exploitation cases.
