As west people don't strict their entire married life to one husband/ onewife.
Here comes the problem , If someone divorces his/her spouse and marries a new person , the new spouse will surely have a awkward feelings on their step children.
So to protect those kids from these new parent , they have coded their penal sections for any kind of beatings or misbehaviour.
Unfortunately , our Indian Parents are fallen to this trap cage in Norway , may be more in future.
P.S: But I support the AP govt Act of "Imprisonment" for Teachers who punish school kids violently.
హే హి , దూల తీరింది , teachers కి .
