ƿ CAP. 43. DE QUARTA SPECIE OBLIGATIONIS, QUAE DICITUR DEPOSITIO.	Chapter 43. On the fourth type of obligation, which is called deposition.
Quarta species obligationis ponitur depositio. Et est depositio obligatio ad sustinendum aliquam propositionem tamquam falsam. Sicut si haec sit vera `rex sedet', et deponas, hoc est sustineas istam tamquam falsam. Unde circa istam obligationem istae sunt regulae: omne depositum sub forma depositi, propositum in tempore depositionis, est negandum; omne antecedens ad depositum est negandum; omne contradicens deposito est concedendum; ad sequens et ad omne impertinens et ad repugnans, quod non est contradictorium nec convertibile cum contradictorio, respondendum est secundum sui qualitatem.	The fourth type of obligation is deposition. And the deposition is an obligation to support any statement as false. For if this is true, `the king sits,' you depose it, that is, you hold it as if it were false. Hence these are the rules regarding this obligation: every deposition under the form of a deposition, intended at the time of the deposition, is to be denied; everything preceding the deposition is to be denied; everything that contradicts must be conceded; to the following and to everything irrelevant and to the contrary, which is neither contradictory nor reversible with the contradictory, must be answered according to its own quality.
