I love B3, but that's nonsense.
The bat size regulations are now part of the laws, like they're literally written there in black and white. They're as much as part of the laws as the lbw rule. The laws of cricket apply to every game of cricket, whether amateur or professional. Unless the game you are playing in has specific exemptions written into the playing conditions, then this applies to you.
I'm not sure how clearer I can make this. What is it that you're not understanding? Do you not understand that they're in the laws, or do you not understand that the laws apply to all forms of cricket unless overruled by specific playing conditions?
MCC has announced specific limitations on the size of cricket bats that will be included in the new Code of Laws.
Bat size limitations to become Law, modes of dismissal to be reduced and language of the Laws to cater for both sexes.
Batsmen will be protected from ‘bouncing bat’ run outs.
New Code of Laws will be the first to be issued since 2000.
After the new Code is issued on 1 October 2017, the maximum dimensions of a cricket bat will be 108mm in width, 67mm in depth with 40mm edges.
The move comes after consultations with bat manufacturers, the Federation of International Cricketers’ Associations, International Cricket Council, MCC World Cricket committee, umpires’ associations and other global governing bodies on the balance between bat and ball.
A bat gauge will ensure that the new limits are adhered to in the professional game, whilst a moratorium period, allowing players to use their existing bats which may be in breach of the Law, will be allowed in the amateur game. The length of the moratorium will be determined by local governing bodies and may vary for different levels of cricketto quote
