TRACK AN APPEAL

The outcome is binding on the operator only.

 The outcome is binding on the motorist and the operator. 

In the context of private parking and appeals to bodies like the Independent Appeals Service (IAS), "conceded" means a party (either the parking operator or the motorist) acknowledges the other party's position and withdraws their claim or appeal, effectively accepting the outcome. 

In a legal context, "allow" means to grant permission, approval, or authorisation for something to happen or be done, or to permit something to be presented or considered. 

If an appeal is dismissed, it means the IAS has reviewed the case has decided the appeal is not valid or successful, and the original decision or outcome remains in place.
