The court in an action filed for the purpose in a related case may also suspend parental authority if the parent or the person exercising the same:
(1) Treats the child with excessive harshness or cruelty;
(2) Gives the child corrupting orders, counsel or example;
(3) Compels the child to beg; or
(4) Subjects the child or allows him to be subjected to acts of lasciviousness.
The grounds enumerated above are deemed to include cases which have resulted from culpable negligence of the parent or the person exercising parental authority.
If the degree of seriousness so warrants, or the welfare of the child so demands, the court shall deprive the guilty party of parental authority or adopt such other measures as may be proper under the circumstances.
The suspension or deprivation may be revoked and the parental authority revived in a case filed for the purpose or in the same proceeding if the court finds that the cause therefor has ceased and will not be repeated. (33a)
