Numerous sources state that the starting point for all common law systems is the cornerstone principle of stare decisis, ie that courts are in similar fact patterns bound to follow previous decisions of their own judicial rank or higher. There are exceptions to this rule but this is fundamentally the starting point.
And yet other sources claim that county court decisions in England and Wales are merely persuasive, rather than binding, upon the county court itself.
Seemingly this requires some rule or exception to be so as it deviates from the starting point. So why wouldn’t the county court create binding precedent for itself, other than the seemingly only practical concern that its decisions aren’t officially recorded in great detail?
