The plaintiff held a large mortgage on apartment property. Upon default in the payment of principal, interest, and taxes a bill of foreclosure was filed against the mortgagor and her grantees who had taken subject to the mortgage. A clause in the mortgage authorized the appointment of a receiver to collect the rents and profits upon default. After hearing, the mortgagee was appointed receiver on the theory that non-payment of taxes constituted waste. Held, that the appointment was unauthorized. Union Guardian Trust Co. v. Rau, 255 Mich. 324, 238 N. W. 166 (1931).
