In all three cases, when the GPS was originally imposed on them, they consented to it. In the two security cases, it was a Federal Court judge who imposed it. In the criminality immigration case, it was an immigration division member who imposed it, along with house arrest and other conditions.
The problem came up two years later. They wanted to get off the GPS and the court wouldn't let them. It's become a crutch that the courts use unnecessarily. I say this in light of the record of compliance during the past five years.
