He had lent it to his son who was caught using it during school hours.

The school, following its disciplinary rules, confiscated it and said it would keep it for three months as punishment.

The school – the Anglo-Chinese School Barker Road – had sent a circular to parents on the ban in January.

According to a report by BBC, the circular said mobile phones “pose a distraction from learning” and asked that students keep all electronic gadgets in their lockers during school hours.

However, on March 21, the student was caught using the phone and it was confiscated.

The boy’s father, Andrew John Hanam, a lawyer, sued the school’s principal for confiscating it, claiming it infringed on property rights.

He is claiming an unknown amount of damages. The case has not been settled yet.

In the meantime, he sought an injunction demanding that the school return his phone as the school rules did not apply to him.

However, a judge has rejected his request for the injunction.

According to BBC, the judge ruled that the confiscation was “justifiable” as the principal was only enforcing the school’s disciplinary rules.
