Definitions and explanations of words or phrases not defined in the text
Delivery stride is the stride during which the delivery swing is made, whether the ball is released or not. It starts when the bowler’s back foot lands for that stride and ends when the front foot lands in the same stride. The stride after the delivery stride is completed when the next foot lands, i.e. when the back foot of the delivery stride lands again.
The addition to the definition of the delivery stride is to take account of the new Law 24.6. The meat of this extra definition has been incorporated into the comment on Law 24.6.
Runs disallowed/not scored. A run to be disallowed is one that in Law should not have been taken. It is not only to be cancelled but the batsmen are to be returned to their original ends. A run not to be scored is not illegal, but one which in Law is not recognised as a proper run. It is to be regarded as not existing, so that the question of cancellation does not arise. It incurs no penalty other than the loss of the run.
There is nothing new in the definition, distinguishing between ‘runs disallowed’ and ‘runs not scored’. It has been inserted for the avoidance of doubt. It is an important distinction, since the batsmen are to be returned to their original ends in one case but not in the other. Each of the relevant Laws states whether sending back is to apply or not.
A deliberate short run is to be disallowed and the batsmen sent back.
An accidental short run is not scored and there is no sending back.
