Laws of Cricket
44. The Use of Headwear Whilst Bowling
44.1 Use of Headwear Whilst Bowling
It is generally not permissible for bowlers to remain wearing headwear whilst undertaking a bowling action. This law sets out the options whereby millenary is allowed and under which circumstances.
44.2 Permissible Uses of Headwear Whilst Bowling
44.2.1 If the weather is above 25 degrees or there is an overhead hole in the ozone layer then headwear whilst bowling is permitted. Furthermore, for those of a ginger persuasion, then such headwear is permitted even when overcast, raining or otherwise inclement
44.2.1.2 The use of a fez is not permitted due to colour clashes with the red ball
44.2.1.3 Headbands are permitted under the proviso that they always look slightly naff.
44.2.2 If the bowler, subject to 44.2.1 is not wearing a hat, then he may involve millenary in the event of taking a hat trick. In these circumstances, the bowler may doff his headwear to those in wider attendance before returning said headgear to the umpire.
44.2.2.1 Similarly to clause 44.2.2, the bowler may utilise headgear in the same way in the event of a significant batting milestone.
44.2.3 Headwear must never be visually distracting. Disco balls as headwear is specifically precluded from featuring in any cricket match following the Great Disco Ball Debacle of '77
44.2.3.1 Similarly, those follically-challenged bowlers are precluded from polishing their domes in such away to as elicit a noticeable and/or distracting glare.
44.3 Dead Ball and Headgear
44.3.1 In the act of bowling, a dead ball shall be called by the umpire in the event that the aforementioned headgear is disturbed in any way during the bowling action.
44.3.1 If, in the act of bowling, the headgear worn by the bowler follows (or precedes) the ball in the direction of the batsman and results in the stumps being disturbed, the bowler is awarded no credit for any resulting wicket.
44.4 Headwear and the Umpire's Role
44.4.1 The umpire must hold any and all headwear that would otherwise be worn by the bowler which would be in contravention of the permissible activities under 44.2
44.4.2 The umpire must always stow all bowling headgear in the overhead compartment - there must always, in the interests of personal hygiene, by headwear of the umpire's own betwixt their head and the disallowed headgear of the bowler
44.4.3 Noting the stipulations above, it is duly noted that in regular circumstances, the umpire must not be seen as a hat stand.
44.5 Appeal by the Batsman
44.5.1 The batsman may appeal against the appropriateness (or otherwise) of any headgear worn by the bowler. The umpire will, considering the clauses noted elsewhere in Law 44, decide whether the bowler's headwear is permissible.
44.5.2 The batsman may not make retrospective appeals regarding headwear in the event of their dismissal. Neither may they refer the headwear to the TV umpire for review.
44.5.3 The batsman may, indeed, find the headwear highly appealing. In such instances, the batsman is allowed to request from the bowler the name of his/her milliner in order to ascertain whether the appealed headgear warrants batsman-investment.
