What is the role of the Government of India in these arrangements?
The Government of India plays a significant role in these arrangements. According to the context provided, when powers and duties have been conferred or imposed upon a State or officers or authorities thereof by virtue of Article 258A, the Government of India is responsible for paying the State such sum as may be agreed, or as may be determined by an arbitrator appointed by the Chief Justice of India, in respect of any extra costs of administration incurred by the State in connection with the exercise of those powers and duties. Additionally, the Governor of a State can entrust functions to the Government of India or its officers under Article 258A, with the consent of the Government of India. Lastly, the Government of India may also undertake executive, legislative, or judicial functions in relation to territories outside India by agreement with the government of such territory, subject to any law relating to the exercise of foreign jurisdiction for the time being in force.
