"While this is a matter on which a decision will be taken by various political parties within Sri Lanka, we will certainly consider its implications and make known to the Sri Lankan authorities our views in the matter," Singh said in a letter to DMK chief M Karunanidhi.
As per the 13th Amendment that followed the Indo-Sri Lankan Accord of July 1987, Sri Lankan government had agreed to devolve some authority to the provinces.
The 90-year-old DMK patriarch on June 9 had written to Singh, expressing apprehensions over "attempts" to abrogate the Rajiv-Jayawardene Accord and repeal the 13th Amendment to the Lankan constitution and sought India's intervention to protect the rights of ethnic Tamils in the island nation.
Karunanidhi had said the amendment was a direct consequence of a bilateral accord between India and Sri Lanka.
