What are the statutory grounds that justify the exercise of the right to litigation, and what are the controls that prevent it from being considered vexatious?

The right to litigation is guaranteed by law for all parties equally. Its exercise is justified if it is based on clear statutory provisions that grant the right to object to specific procedures or decisions. A lawsuit is not considered vexatious if it is based on a sound statutory basis and a legitimate interest, and its objective was not to inflict harm upon the other party, but rather to protect the statutory rights of the litigant.
