The main legal point established is that exchanges of tarwad properties are covered by S.25 of the Nayar Act and must be supported by consideration and necessity. Additionally, the principles of equity in S.64 and 65 of the Contract Act were applied in decreeing cancellation of alienations.

1. These two appeals have arisen in O. S. No. 34 of 1956 on the file of the Subordinate Judge, Attingal, A. S. No. 228 of 1959 by the 1st defendant and A. S. No. 446 of 1959 by the 3rd defendant. The suit is to set aside certain alienations of immovable property belonging to the tarwad of the plaintiffs, executed by the 10th defendant, their mother. Exts. P. 1 to P. 4 evidence sales to the 1st defendant of suit items 1 to 4; Exts, P. 5 to P. 7 evidence sales of items 5 to 8 to the 2nd defendant; and Exts. P. 8 and P. 9 are copies of deeds of exchange of suit items 9 and 10 with properties, not scheduled in the plaint, of the 3rd defendant and her late husband whose interests are now vested in defendants 3 to 8. All the alienations were impugned, under S.25 of the Travancore Nayar Act, 1100, as wanting in consideration and tarwad necessity. The 1st defendant did not contest the suit. Defendants 2 and 3 asserted the alienations in their favour to be supported by consideration and necessity. The court below upheld Ext. P. 5, set aside Exts. P. 6 and P. 7 on condition of return of considerations found, and cancelled Exts. P. 1 to P. 4, P. 8 and P. 9 as not been supported by consideration and necessity. Defendants 1 and 3 have come up in appeal.

2. The 1st defendant has not cared to discharge the burden on him to show the assignments in his favour, Exts. P. 1 to P. 4, to be supported by consideration and tarwad necessity. The court below has on plaintiffs' evidence found the alienations in his favour as not been supported by consideration and tarwad necessity. There is no material for us to differ therefrom. The prayer for remand to enable him to put forward his contentions hereafter cannot be allowed as it was indifference on his part not to have entered appearance at the proper time and contested the suit. His appeal has therefore to fail.

3. As regards the exchanges of tarwad properties with properties of defendants 3 to 8, the only necessity recited in the documents and relied at the Bar is convenience of enjoyment. Counsel for the 3rd defendant contended that S.25 of the Nayar Act deals with sales, mortgages and leases only and that exchanges do not come within its purview and therefore need not be shown to be supported by consideration and necessity to bind the tarwad. We do not feel persuaded by this nice distinction whose only merit is the ingenuity of the counsel. In the context in which the word 'sale' appears in S.25 of the Nayar Act, it is obviously used in a rather generic sense to mean an outright alienation. All alienations of tarwad properties are purported to be covered by S.25 and 26 of the Act, but the only words used therein are sales, mortgages and leases. It is not then clear that, in the context, the word 'sale' covers all absolute alienations, 'mortgage' means all encumbrances in favour of creditors, and 'lease' denotes all grants of under rights in immovable property. Exchanges are really a specie of sales, and the only difference between a sale stricto sensu and a sale in the form of exchange lies in the consideration which is money in one and equivalent property in the other. It is a very familiar principle in law that one cannot do that indirectly which one is prohibited from doing directly. If an absolute alienation for a price is prohibited, to an equal extent must an absolute alienation for another property be held prohibited. The fact that sales and exchanges are treated separately in the Transfer of Property Act is of no consequence in construing the Nayar Act, as the two enactments are not in pari materia. An exchange of tarwad immovable property for a property of another is well within the mischief of S.25 of the Travancore Nayar Act, 1100. It follows that such an exchange cannot be made by a karnavan unless it be for adequate tarwad necessity. Mere convenience of enjoyment, which must necessarily vary according to the whims and fancies of particular individuals, cannot b
