They’re gonna do the delay tactic too but this is more insidious.
The amount of money the husband is asking for isn’t all that much, pennies to them and in the greater scheme of things this is a nothing suit to them, low stakes. Since it’s low stakes they’re trying this tactic first to see if it’ll stick and create that dangerous precedent. I don’t suspect it’ll go through but with all these right wing pro capitalist judges it might, and it’s worth trying for them since it’s such a low stakes suit.
