laid down either in the Evidence Act or in the Transfer of Property Act. But a court may presume under Section 114 of the Evidence Act that under certain circumstances a loan and a deposit of title deeds constitute a mortgage. But that is really an inference as to the existence of one fact from the existence of some other fact or facts. Nor the fact that at the time the title deeds were deposited19 there was an intention to execute a mortgage deed in itself negatives, or is inconsistent with, the intention to create a mortgage by deposit of title deeds to be in force till the mortgage deed was executed. The decisions of English Courts making a distinction between the debt preceding the deposit and that following it can at best be only a guide; but the said distinction itself cannot be considered to be a rule of law for application under all circumstances. Physical delivery of documents by the debtor to the creditor is not the only mode of deposit. There may be a constructive deposit.
