An eight-year-old boy has sparked an unlikely outcry in Sweden after failing to invite two of his classmates to his birthday party.
The boy's school says he has violated the children's rights and has complained to the Swedish Parliament.
The school, in Lund, southern Sweden, argues that if invitations are handed out on school premises then it must ensure there is no discrimination.
The boy's father has lodged a complaint with the parliamentary ombudsman.
He says the two children were left out because one did not invite his son to his own party and he had fallen out with the other one.
The boy handed out his birthday invitations during class-time and when the teacher spotted that two children had not received one the invitations were confiscated.
"My son has taken it pretty hard," the boy's father told the newspaper Sydsvenskan.
"No one has the right to confiscate someone's property in this way, it's like taking someone's post," he added.
A verdict on the matter is likely to be reached in September, in time for the next school year.
