A large spectroscopic survey Hi-z spectroscopy of SNe is being carried on 8m class telescopes (Gemini, VLT, Keck). The primary goal is to obtain Supernova identification and redshift. Detailed spectroscopy of a subsample of distant SNe is also done to validate the use of Type Ia SNe as cosmological candles. This program yielded information on SNLS-03D3bb.
