Loans to Persons under Power
An interesting restriction on the power of making loans was created by the Senatus Consultum Macedonianium passed during the early Empire. This enactment rendered loans to persons under power not actionable. According to Justinian the statute was passed because it was found that persons in power loaded down with debt for money borrowed and squandered often plotted against the lives of their parents. Presumably upon the death of their parents they would inherit means of paying their debts.
This statute did not make loans to persons in power void, but only denied an action to the lender. If the loan was repaid without action, the money could not be recovered back on the plea that it was not owed.
The statute applied only to loans of money, and certain cases were exempted from its operation, namely, loans on the son's peculhim, or made with the father's consent, or for the benefit of the father's estate, or for necessaries, or in the honest belief of the lender that the borrower was sui juris.
