§ 1810-A. Limitation on right to resort to commercial claims\nprocedures. If the clerk shall find that the procedures of the\ncommercial claims part are sought to be utilized by a claimant for\npurposes of oppression or harassment, as where a claimant has previously\nresorted to such procedures on the same claim and has been unsuccessful\nafter the hearing thereon, the clerk may in his discretion compel the\nclaimant to make application to the court for leave to prosecute the\nclaim in the commercial claims part. The court upon such application\nmay inquire into the circumstances and, if it shall find that the claim\nhas already been adjudicated, or that the claim is sought to be brought\non solely for purposes of oppression or harassment and not under color\nof right, it may make an order denying the claimant the use of the\ncommercial claims part to prosecute the claim.\n
