-A plea pleaded in an action of debt only, brought by a lessor against lessee for years, or at will, without deed. If both lessee and lessor executed a lease, the former was estopped from pleading this plea to an action of debt for rent by the lessor. It has, however, been held to be a good plea on a demise by deed poll, because as to the lessee, it is no estoppel. It could be pleaded by a lessee in any case where occupation was enjoyed, for a tenant cannot impeach his landlord's title. In debt on bond conditioned for the payment of rent reserved upon a demise according to certain articles, the defendant is Nihil magis justum est quam quod necessarium est (Dav. 12): Nothing is more just than what is necessary.

Nihil peti potest ante id tempus quo per rerum naturam persolvi possit (D. 50, 17, 186): Nothing can be demanded before the time when, by the nature of things, it can be paid. Nihil possummus contra veritatem (Doct. & S. dial. 2, c. 6): We can do nothing against truth. Nihil præscribitur nisi quod possidetur (Lord Hale, "De jure maris" 32): Nothing is prescribed except what is possessed. Nihil quod est contra rationem est licitum (Co. Litt. 97): Nothing is permitted which is contrary to reason. Nihil quod est inconveniens est licitum (Co. Litt. 66a): Nothing that is inconvenient is allowed. In other words, the law will sooner suffer a private mischief than a public inconvenience. Nihil simul inventum est et perfectum (Co. Litt. 230): Nothing is invented and perfected at the same moment. Nihil tam conveniens est naturali æquitati quam unumquodque dissolvi eo ligamine quo ligatum est (2 Inst. 359): Nothing is so consonant to natural equity as that a thing should be dissolved by the same means by which it was bound. Nihil tam conveniens est naturali æquitati quam voluntatem domini rem suam in alium transferre ratam habere (1 Co. 100): Nothing is so consonant to natural equity as to regard the intention of the owner in transferring his own property to another. estopped from saying that he had not anything Nihil tam naturale est, quam eo genere quidque dissolvere, quo colligatum est; ideo verborum obligatio verbis tollitur, nudi concensus obligatio contrario consensu dissolvitur (D. 56, 17, 35): Nothing is so natural as to dissolve anything in the way in which it was bound toin the land demised by the articles. In debt for rent by husband and wife, upon a lease by her and her first husband, it is a good defense that her husband was solely seised, and that she had nothing in the land.

(10 edit.) 677.

Nihil tam proprium est imperii quam legibus vivere (2 Inst. 63): Nothing is so much the property of sovereignty as to live according to the laws.
