The treaty came into force on August 8, 1973 and expired on July 1, 1974. Under the agreement, UNHCR oversaw the repatriation of citizens from Bangladesh and Pakistan. According to the UN, 121,695 Bengalis have been transferred from Pakistan to Bangladesh. Among them are senior Bengal officials and the military. 108,744 civilians and non-Bengali officials were transferred from Bangladesh to Pakistan.  India released 6,500 Pakistani PoWs, most of whom were transported by train to Pakistan. In 1974, General Niazi was the last Pakistani officer to be symbolically returned by the Wagah border.  Although the agreement called for the repatriation of the Biharis to Bangladesh, the Pakistani government withdrew its promise to relocate the Community to Pakistan.  This led to the stateless Pakistani community stranded in Bangladesh.
The Delhi Agreement was a trilateral agreement signed on 28 August 1973 between India, Pakistan and Bangladesh. and only ratified by India and Pakistan.  It allowed the repatriation of prisoners of war and interned officials held in the three countries after Bangladesh`s war of liberation in 1971. The agreement was criticized because Pakistan did not repatriate Urdu spokesmen to Bangladesh and failed to bring to justice 195 high-ranking military personnel accused of being admitted to the war.  There was total agreement on the position of the Sadar-i-Riyasat; Although the Sadar-i-Riyasat was chosen by state law, it had to be recognized as such by the Indian president before its installation; In other Indian states, the head of state was appointed by the president and, as such, his candidate, but the person who was to be appointed head had to be an acceptable person to the government of that state; No one who is not acceptable to the government can be pushed on the state as head of state. The difference in the case of Kashmir lies solely in the fact that Sadar-i-Riyasat is elected primarily by the legislative branch of the state itself, instead of being a candidate of the government and the president of India. With regard to the powers and functions of the Sadar-i-Riyasat, the following argument was agreed upon by mutual agreement Representatives of the Government of Kashmir were transferred with representatives of the Indian government and reached an agreement to support the main decisions of the Constituent Assembly of the State J-K. This agreement later became known as the Delhi Agreement, 1952. The main features of this agreement were that among the PoWs, 195 Pakistani military officers detained in India were identified as the main suspects of war crimes. Pakistan insisted that they be released as one of its main demands. She urged several Muslim countries to refuse recognition of Bangladesh until the release of the 195 officers.  India preferred their repatriation to Pakistan.
In the text of the agreement, Bangladeshi Foreign Minister Kamal Hossain said that only four states – Saurashtra, Travancore and Cochin, Mysore and J-K – have chosen this option and have created their own constituent assemblies. Three of these states have not defined their Constitutions, and J-K was the only one to form its own Constituent Assembly and formulate their Constitution, which still exists today. he may resign by writing under his hand to the President; . It provided that Sections 356 and 357 did not apply to the J-K State. What would have been the situation in 1989, when the Pakistan-sponsored “death by a thousand incisions” would have engulfed the entire Kashmir Valley – if the Indian president had not declared the president`s reign in J-K? Moreover, Sheikh Abdullah`s National Conference did not really cover itself with glory when autonomy was first achieved in 1950.
