Summarize the following court judgment. Civil Appeal No. 862 of 1968. Appeal by special leave from the Judgment and order dated the 6th December	 1964 of the Punjab & Haryana High Court in Civil Writ No.587 of 1964. G. L. Sanghi and Girish Chandra for the Appellants. section N. Anand for the Respondents. 79 The Judgment of the Court was delivered by GUPTA	 J. This appeal by special leave arises out of a proceeding under the (hereinafter referred to as the Act). The only question for determination in the appeal is whether the deletion of rule 30 of the Displaced Persons (Compensation and Rehabilitation) Rules	 1955 (hereinafter referred to as the Rules) with effect from August . 13	 1963 made any difference to the rights of the parties concerned in this case. The question arises on the following facts. Shop No. 2 in Tripri township in Patiala which is a government built property was allotted in 1950 to the first respondent Khillu Ram jointly with one Tara Chand and his son by the Custodian of Evacuee Property. In 1951 both Tara Chand and his son Left Tripri to settle elsewhere and the second respondent Teju Mal applied for allotment of their share in the shop to him. By his order dated November 11	 1959 the Managing officer	 Tripri and Rajpura	 held that Teju Mal and Khillu Ram were in possession of the shop as allottees respectively of 2/3 and 1/3 shares therein. Aggrieved by the order of the Managing officer	 the first respondent Khillu Ram preferred an appeal to the Settlement officer	 Jullundur	 who by his order dated February 12	 1962 set aside the order of the Managing officer and remanded the case for a fresh decision under rule 30 of the Rules. Rule 30 is in these terms: " Payment of compensation where an acquired evacuee property which is an allotable property is in occupation of more than one person. If more persons than one holding verified claims are in occupation of any acquired evacuee property which is an allotable property	 the property shall be offered to the person whose gross compensation is the biggest and the other persons may be allotted such other acquired evacuee property which is allotable as may be available :" This rule has a proviso and an explanation none of which is relevant for the present purpose. After remand the case was transferred to the Assistant Settlement officer who found that the gross compensation payable to the first respondent was higher than that of the rival claimant	 Teju Mal and in terms of rule 30 allotted the entire shop to the first respondent by his order dated November 27	 1962. A revision petition against this order made by Teju Mal was dismissed by the Deputy Chief Settlement Officer on September 5	 1963. In the meantime	 as stated already	 rule 30 had been abrogated with effect from August 13	 1963. Teju Mal then moved the Central Government under sec. 33 of the Act. Teju Mal 's application under sec. 33 was heard on February 25	 1964. The effect of deletion of rule 30 was that the properties which were in the occupation of more than one person were to be put to sale. The Joint Secretary to the Government of India who heard the application under sec. 33 held that the case should be governed by the Rules as amended in 1963 excluding rule 30	 and accordingly by his order dated February 80 26	 1964 he set aside the order allotting the shop to the first respondent Khillu Ram and directed the property in question to be put to sale. The first respondent filed a writ petition in the Punjab High Court for quashing the order passed under sec. The Punjab High Court held that the subsequent deletion of rule 30 did not affect the existing rights of the first respondent and quashed the order of the Central Government made under sec. The correctness of this ` order is challenged in the appeal before us which has been preferred by the Union of India and several other authorities concerned with the administration of the . The only submission made by Mr. Sanghi appearing for the appellants is that rule 30 was a rule of procedure and its deletion in 1963 affected only the mode of proceeding by which the rival claims of Khillu Ram and Teju Mal was to be decided. It was argued that amendment of the Rules in 1963 deleting rule 30 being procedural in character would affect the proceeding between the two respondents then pending	 and their rights	 it was submitted	 should therefore be decided on the footing as if Rule 30 had never been in force. We are unable to accept this submission. The Act provides for the payment of compensation and rehabilitation grants to displaced persons and matters connected therewith. Under the Act a displaced person has a right to get compensation in the form and manner prescribed by the Act and the Rules framed thereunder. Rule 30 is in Chapter V of the Rules which deals with payment of compensation by transfer of acquired Evacuee Properties. Though the shop in question is a government built property and not an acquired evacuee property	 rule 43 in Chapter VI of the Rules which provides for payment of compensation by transfer of government built property says that the "pro visions of rules 25 to 34 shall	 so far as may be	 apply to the transfer of any Government built property or Government plot under this Chapter". Rule 30 prescribes that where the property is in the occupation of more persons than one	 it shall be offered to the person whose gross compensation is the highest. Clearly rule 30 deals not with the form of procedure but with a substantive right conferred by the Act on displaced persons. Mr. Sanghi described this rule as only a mode or manner of payment of compensation. This may be so	 but the form and manner in which compensation is payable is also part of the right to get compensation. Rule 30 is not an instrument or machinery for asserting the right conferred by the Act; it does not regulate the procedure for settlement of disputes concerning that right. Therefore	 the deletion of the rule in 1963 cannot affect pending actions. The rights of Khillu Ram and Teju Mal must be governed by rule 30 which was in force in 1959 when the dispute arose and was decided by the Managing officer. A full Bench of the Punjab and Haryana High Court in Pt. Dev Raj vs Union of India & ors.(1) considering the same question which arises for determination in this appeal	 held that "a displaced person has a right to the determination of his claim for compensation and its satisfaction in the 1) A. I. R. 81 prescribed manner and this is a substantive right"	 that so far as rule 30 is concerned "the right which a displaced person claims under this rule . cannot be adversely affected or taken away unless it is expressly stated in the amending provision	 or the language of the Act This	 in our opinion	 is a correct statement of the law. Neither by express words nor by implication the amendment of the Rules in 1963 deleting rule 30 has been made retrospective in operation. For these reasons the appeal fails and is dismissed but without any order as to costs. V.P.S. Appeal dismissed.

Rule 30 of the Displaced Persons (Compensation and Rehabilitation) Rules	 1955	 prescribes that where property is in the occupation of more persons than one	 it shall be offered to the person whose gross compensation is the highest. A particular property was allotted under this rule to the first respondent. A revision petition by the rival claimant	 was dismissed ill September	 1963. But on August 13	 1963	 the rule had been abrogated. The effect of the deletion was that a property in the occupation of more than one person was to be put to sale. In an application under section 33 of the 	 by the rival claimant	 the appellant held that the case should be governed by the rules as amended	 that is	 excluding r. 30	 and set aside the order allotting the premises to the first respondent. A writ petition filed by the first respondent in the High Court was allowed. In appeal to this court	 the appellant contended that the rule was one of procedure and its deletion affected only the mode of proceeding by which the rival claim was to be decided. Dismissing the appeal	 ^ HELD: The rights of the two rival claimants must be governed by r. 30 which was in force when the dispute arose and was decided by the authorities under the Act. [80 G H]. (a) Rule 30 deals	 not with form of procedure	 but with the substantive right conferred by the Act on displaced persons. The Act provides for the payment of compensation and rehabilitation grants to displaced persons and matters connected therewith. Rule 30 is in Chapter V of the Rules which deals with payment of compensation by transfer of acquired evacuee properties. Assuming that the rule is only a mode or manner of payment of compensation	 the form and manner in which compensation is payable is also a part of the right to get compensation. The rule is not an instrument of machinery for asserting a right conferred by the A t. it does not regulate the procedure for settlement of disputes concerning that right. Therefore	 the deletion of the rule in 1963 cannot affect pending actions	 [80 D G]. (b) Neither by express words nor by implication the amendment of the rules in 1963 deleting r. 30 has been made retrospective in operation. [81 A B]. Dev Raj vs Union of India & ors.
