Rules on Point in Parliamentary Debate

• Point of Privilege: Pertains to noise, personal comfort, etc. - may interrupt only if necessary.
• Point of Information or Clarification: Generally applies to information desired from the speaker: "I should like to ask the (speaker) a question."
• Point of Order: Infraction of the rules, or improper decorum in speaking. Must be raised immediately after the error is made. 
• Point of Contention: Where the speaker misquotes or misrepresents previous content in the case, this can be called out by the contender. 

Each point is addressed by standing and declaring which point one wishes to make. It's interesting to note that no eye contact is made between the speaker and the contender. All delivery is done to the Speaker of the House and the House itself.
