You're definitely not allowed lifts in a rumba on SCD.
American Smooth, Salsa, Charleston, Argentine Tango, Showdance and swing/rock&roll (if they do that) are the lift dances. Have I forgotten any?
Any other dances you should in theory get docked a point for a rules violation and that was a very blatant lift - not one of those where the woman is meant to sweep the floor with her toe but doesn't quite manage it, or an over enthusiastic "assisted jump".
