In a government sense in the States, a point of order can be made during floor proceedings in either the
House of Representatives or the
Senate when one of our esteemed elected officials asserts that the rules of procedure are being violated.
The point of order then halts the proceedings while the presiding officer/chair rules on whether or not it is valid.
In the Senate, the chair's ruling may be appealed by any Senator. The Senate then votes on the appeal and it it not uncommon for the chair to be overturned.
In the grand tradition of the House of Representatives, appeals are also possible but very rarely entered and almost never succeed.
