What is an illegal bowling action?
An illegal bowling action is one in which the bowler's 'elbow extension' exceeds 15 degrees while he is in his delivery stride. The ICC set the 15-degree limit for all bowlers in November 2004.
What constitutes elbow extension?
Elbow extension includes flexion (in this case, the closing of the elbow joint) and extension (the straightening of the elbow joint).
Does a bent arm automatically signify an illegal action?
If the arm is bent at the onset of the delivery stride but remains rigid or does not flex or extend beyond the permissible 15 degrees during the duration of the stride, the action is not illegal. An action is only illegal if the arm flexes or extends beyond the permissible limit while in the delivery stride.
