Mutual protective orders are prohibited unless both parties have filed a petition under part three of this article and have proven the allegations of domestic violence by a preponderance of the evidence. This shall not prevent other persons, including the respondent, from filing a separate petition. The court may consolidate two or more petitions if he or she determines that consolidation will further the interest of justice and judicial economy. The court shall enter a separate order for each petition filed: Provided, That nothing in this section shall preclude the court from entering an order restricting contact pursuant to section two-a, article two-a, chapter fifty-one of this code.
