Constraints are applied from top to bottom in the Constraints Root folder in the Scene browser. That is, constraints at the bottom of the list are applied last.
To change a constraint’s priority:
If two constraints affect the same model, the constraint closest to the bottom overrides any earlier constraints. However, two separate constraints can influence different properties of a model. For example, if you create a Relations constraint to change the rotation of a cube, and follow it with a Position constraint to change the marker’s position, the marker is rotated using the first constraint and translated using the second constraint. If the second constraint was a Rotations constraint, it would override the Relations constraint. For more information, see Common constraint settings
