I am Appealing a child support order. Among other issues, there was a material mistake made by the court and I am asking the order be considered void and or that it is voidable and should be voided (Civ. Rule 60.02). I briefed my argument. The father's attorney simultaneously filed a motion to dismiss and his reply brief. He asserts I don't have a claim (no procedural errors like service, filing ,etc). He has taken me to court over child support 2007, 2008, 2010 and 2012. What reason, other than harassment, would he have to file both of these together when relief is clearly "plausible" particularly in consideration of the equitable nature of child support?
