Explanation:

• One of the Sarkaria Commission's key recommendations was to establish a permanent Inter-State Council. 

• Inter state council is an independent national consultative forum having a clearly defined mission in conformity with Article 263 of the Indian Constitution.

• The interstate council was established as a robust institutional framework for promoting and supporting cooperative federalism. 

• The inter-state council is a recommendatory body that has been empowered to investigate and discuss subjects of common interest between the Union and state(s), or among states.

Hence both statements are correct.
