The said park was to be established at Pragati Maidan.

( 4 ) ON 28th January, 1984, Trade Fair Authority of India (for short 'tfai') took a final decision to allot land to IAL on licence basis, as TFAI was a lessee under the Government of India in respect of the aforesaid land on which it was decided to establish an amusement park. On 6th December, 1984 a letter was written by the TFAI to IAL intimating them that initially the area would be licensed to IAL on the similar lines as licenced to State Governments and central Ministries who had/are setting up permanent pavilions at Pragati Maidan. It was also stated therein that the premises would be handed over to IAL on permanent lease basis subsequent to the renewal of lease deed of.

Clause 2. ii of the said letter indicated that the land with permanent buildings measuring about 40 acres may be allotted to the tfai on a 99 years lease on payment of premium at the rate of Rs. 6 lacs per acre and annual ground rent at the rate of 2. 5% of the said premium. It was further stipulated in clause 2. iv of the said letter that the TFAI had licensed out an area of about 16 acres in Pragati Maidan Complex to M/s. International Amusement limited, for setting up an amusement park. It was also stated that for this land the TFAI would be charged an annual licence fee at the rate of Rs. 400 per acre commencing from the date on which the licence was granted by them to the company.
