The High Court issued the order yesterday, acting on a PIL submitted by Mizoram-based civic organisation SOSA (Society for Social Action) three years back.
SOSA president and retired IAS officer S L Sailo said the organisation filed the PIL in 2007 for a probe into the PMGSY projects from 2001 to 2005 as there appeared a ''mismanagement'' of funds during this period.
The High Court instructed that an interim report be submitted to the state chief secretary who will further take necessary actions.
The SOSA had stated in the PIL that ''works under the PMGSY in Mizoram were sub-standard and did not meet the norms.'' In some cases, old roads were reported as newly-constructed under the PMGSY.
Earlier this year, the High Court had ordered a CBI probe into the alleged compensation scam in the Tuirial hydel project.
