We give an update of current research on the use of nebular spectra of SNe la as distance indicators. Results of the application of the method to a group of SNe la are reported. We describe the status of the research including theoretical and observational requirements of the method. Our results point toward a shorter distance scale than methods based on the “standard candle” hypothesis for Type la SNe.
