In DPP v. Egan (1989), what did X do that led to the charge of procuring drunk driving?

In DPP v. Egan (1989), the charge of procuring drunk driving was based on the act of adding alcohol to Y's drink. This action is significant because it directly contributed to impairing Y's ability to drive safely. The prosecution in such cases aims to establish that the individual not only facilitated the act of driving but did so in a manner that consciously increased the likelihood of legal intoxication, thereby endangering public safety.

By adding alcohol to Y's drink, X took a proactive step in influencing Y’s state and consequently their capacity to operate a vehicle. This act indicates a clear intent to cause or contribute to Y's intoxication, which is a key element in cases of procuring drunk driving. It demonstrates not just a passive involvement but an active engagement in encouraging or enabling another to commit an offense.

Other options may involve behaviors that could contribute to unsafe driving, such as encouraging reckless driving or providing a vehicle. However, these do not directly establish the procuring element in the same manner as directly influencing someone’s intoxication does. In this context, the act of physically altering Y's drink to include alcohol is a more direct and legally relevant involvement in procuring drunk driving.
