Consequences for children

This is in Quebec Canada - A 12 yr old girl sues her father(seperated from her mother) to let her go to a graduation trip. The father had grounded her as a punishment. For full report click here

Surely parents have a right to give their children consequences to their actions.

Lots of questions raised in my head -
Where's the father-mother relationship at ? Who supported/encouraged the girl to go to court and why ?
What did the girl do to have the consequence of not be able to go on the trip ?

And relecting on my parenting are the consequences we apply fair and constructive?

Food for thought ...
