213. Cases to which creditors may not vote.- A creditor shall not vote in respect of any unliquidated or contingent debt, or any debt the value of which is not ascertained, nor shall a creditor vote in respect of any debt on or secured by a current bill of exchange or promissory note held by him unless he is willing to treat the liability to him thereon of every person who is liable thereon antecedently to the company, and against whom no order of adjudication has been made, as a security in his hands, and to estimate the value thereof, and for the purposes of voting, but not for purposes of dividend, to deduct it from his proof. |
