How to Appeal a PCN for a Broken Pay Machine or Payment App Failure

Unable to pay because the parking meter was broken or the app failed? Learn how to prove payment impossibility and cancel your fine.

Appealing a Fine When Payment Equipment Failed

If a parking ticket machine or pay-and-display meter was broken, out of order, rejected coins, or the cashless phone app (RingGo, PayByPhone, MiPermit) suffered a server outage, you are legally protected under the doctrine of impossibility and procedural fairness.

Doctrine of Impossibility (Lex Non Cogit Ad Impossibilia)

The law does not compel a motorist to perform an impossibility. If the issuing authority or operator failed to maintain functioning payment equipment, they cannot penalise a driver for non-payment where no viable alternative existed.


Step 1: Evidence Required

  • Photo of the machine display: Showing "Out of Order", blank screen, or coin slot jammed.
  • Machine identification number: Located on the front or side of the meter.
  • Screenshots of App errors: Showing timeout errors, transaction failed notifications, or network failure logs from PayByPhone / RingGo.
  • Call logs / SMS logs: If you attempted to call the automated IVR payment line.

Step 2: Appeal Strategy

  1. For Council PCNs: Cite procedural failure and request the council's maintenance log for the meter on the date in question. Councils are required to keep audit records of reported machine faults.
  2. For Private PCNs: State that payment was frustrated due to operator equipment failure, and cite BPA Code Clause 18.
