In our legal system, lower courts (or tribunals) are bound by the decisions of higher courts. When a higher court makes a decision, it is then a binding precedent (unless, of course, it is then overturned by an even higher court).
E.g., the Supreme Court can bind the Court of Appeal (and every court below it), the Court of Appeal can bind the Employment Appeal Tribunal (and the Employment Tribunal below it) and the Employment Appeal Tribunal can Appeal the Employment Tribunal.
If a decision is made by a court/tribunal at the very lowest rung, then it cannot be a binding precedent. The Patrick Lee decision was made at the lowest possible level so it does not bind any future decision maker (at the most, it could be cited as being persuasive, but it isn't binding).
I do think its the right decision and correctly interprets the Forstater decision, it just isn't of much legal significance.
And it wasnt very widely reported. It was picked up by the Mail, the Express, the Telegraph and GB News.
Other news sources, from the left, right and centre, did not cover it.
