Using systematic observation together with an analysis of the relevant
court and criminal records this research examined the processing and
sentencing of a small number of male and female defendants in an Engli
sh magistrates' court. The findings indicate that sentencing was indir
ectly affected by a defendant's sex and directly affected by at least
one aspect of a defendant's demeanour. These results provide support f
or the view that combining systematic observation with an analysis of
court records offers a more effective means of investigating the diffe
rential treatment of male and female defendants than either unsystemat
ic observational studies or the analysis of court records alone.
