We report the spectral lag analysis for GRB 120403A (Beardmore, et al., GCN Circ. 13191)
based on the BAT data. Using 64-ms binned light curves, the spectral lag
for the 15-25 keV to 50-100 keV bands is 63 +380/-180 msec. Because of a relatively
large error in the lag measurement due to a weak nature of the burst, we can not
conclusively say that this burst is in the short burst category.
