A city council ruled that the teacher, whose identity was not revealed, was correct in forcing the child to rescind the invitations since school policy mandates a student invite all members of a class or none at all, The Local said Thursday.

Lena Leufstedt, the council's administrative chief manager for schools, said the unidentified male student did not invite two of his classmates to his July party and therefore violated school policy.

"This is accepted practice at pre-schools and school within the district presided over by the board," Leufstedt said.

The boy's father told the Local the teacher's actions were ill-advised given the situation.

"My son took it pretty hard. No one has the right to confiscate someone's property in this way, it's just like taking someone's mail," he told the newspaper.
