The court made several important observations: (1) There are three types of police traps - passive detection traps (like speed traps), traps for ongoing criminal activity (like catching illegal liquor sellers), and dangerous inducement traps (like bringing contraband to suspects and inviting purchase) - only the third category is problematic and open to abuse; (2) The detection of crime, particularly corrupt practices, must be achieved not by luring suspects into committing offences, but by setting up lawful traps that only serve to prove that a crime has indeed been committed; (3) Not all constitutional rights are absolute, but their restriction has to be proportionate to the means that it seeks to achieve; (4) Sentencing an officer of the court who engages in criminal conduct to anything other than imprisonment would be "wholly inappropriate" as such conduct "puts the entire justice system into disrepute"; (5) The shifting nature of the appellant's defences (from refund claim, to denial, to constitutional challenge) suggested the constitutional arguments were raised as an afterthought rather than genuine legal concerns.
