Players sometimes ask— Is a wooden sideboard an obstacle? What they mean is— If the circle is close to a sideboard, should we move it? The question comes up because there is a concern that a squat pointer or a player in a wheelchair might hit a hand on the sideboard when throwing.
On “Ask the Umpire” Mike Pegg has given different anwers to this question at different times. First he ruled that a sideboard is not an obstacle— a concerned squat pointer must stand, not squat, when pointing. Later he stated that a sideboard higher than 20cm is an obstacle because “at this height or higher it may impede a player.” Still later he stated that a board of 25cm is an obstacle.
The problem here is that the FIPJP rules never define the word “obstacle”, so it’s an open question whether any particular thing (such as a sideboard) is a throwing obstacle. So we need to begin by defining “throwing obstacle”. I propose this— something that might prevent a player from throwing with his normal throwing form, or something that might cause injury to a player if he plays with his normal throwing form.
Once we’ve defined our terms, the answer to the question depends on the particular circumstances. In normal circumstances a wooden sideboard is not considered an obstacle. But in a situation where it might prevent a player from throwing with his normal throwing form, or might cause injury to a player if he plays with his normal throwing form, then it should be considered an obstacle and the circle should be moved away from it. So the answer to the question is:
Normally a wooden sideboard is not considered to be a throwing obstacle, but in some cases it is.
Moving the circle away from a throwing obstacle is something that should be done before the jack is thrown. That means that if one of your team’s players is a squat pointer or in a wheelchair, and you’re concerned about the wooden surround, don’t hesitate— SPEAK UP! Don’t wait until after the jack has been thrown to voice your concerns, because by then it is too late.
