Liverpool Airport PCN second stage.

Hi I copied the appeal letter as advised and received this reply. What is the next stage for me. Some background information. I picked my sister up from Liverpool Airport stopped on the road and she jumped in. I was stationary for 11 seconds. My partner who is the registered keeper then received the PCN.

Here is the letter

We acknowledge receipt of your appeal (representations) received 5th December 2014 in relation to the above Parking Charge Notice (PCN).

Please note that we are proceeding on the reasonable assumption that you were the driver of the vehicle on the date in question unless you are able to prove the contrary.

Whilst we understand your concern at receiving a Notice, it is entirely the motorists responsibility to ensure that they adhere to the Terms and Conditions of use for the airports private access roads.

The roadway in question is part of a high security zone and as such motorists are clearly advised not to park, stop or wait on double yellow lines, red route zones or roadways at any time. Such actions may also pose an obstruction or danger to other road users. There are numerous warning signs in place along the private access roads.

In response to your comments, we can confirm that on the 23rd November 2014, you stopped your vehicle in a prohibited area. Please be advised that our signage located throughout the area clearly state "No Stopping At Any Time". It is the motorist's responsibility to ensure that he/she is fully aware and compliant with the Terms and Conditions of this area.

You have raised a number of points in your appeal which are not appropriate for us to deal with at this stage. Please note that, as members of the Independent Parking Committee (IPC) it is necessary for us to evidence to the IPC that we have relevant authority to undertake enforcement activity at the site concerned and that our signs in situ are compliant in setting out the relevant terms and conditions of use. We will defend the points you have raised as appropriate should the matter proceed to the Independent Appeals Service IAS and/or court. We have therefore dealt with the pertinent points in your appeal below."

We are satisfied that the Parking Charge Notice has been issued correctly and your appeal (representations) is therefore rejected. We will not accept any further appeals.

They have advised us that we should either pay the fine or if we believe the decision is incorrect we can appeal to the Independent Appeals Service (IAS).

What is the next plan of action?
Thanks for any help or advise you may provide.
