It’s always satisfying to find a preliminary point that knocks out a claim, usually it is a time point ie an unfair dismissal has been presented outside of the three month limitation period.
The term knockout point is frequently used by both representatives, clients and sometimes Tribunal panels. Tribunal cases sometimes do have a sporting feel to them with one party or another either having a knock out point or winning on points. Pre case manouevres are like sparring, you are softening your opponent up before delivering a right hook, which you hope will put them on the canvas.
Reading this does put the use of boxing analogies for Tribunal cases into some sort of context (and insignificance).
