GRB 091127 is a bright gamma-ray burst (GRB) detected by Swift at a redshiftz=0.49 and associated with SN 2009nz. We present the broadband analysis of theGRB prompt and afterglow emission and study its high-energy properties in thecontext of the GRB/SN association. While the high luminosity of the promptemission and standard afterglow behavior are typical of cosmological long GRBs,its low energy release, soft spectrum and unusual spectral lag connect this GRBto the class of sub-energetic bursts. We discuss the suppression of high-energyemission in this burst, and investigate whether this behavior could beconnected with the sub-energetic nature of the explosion.
