Spokesman Dana Doiron says Kevin Murphy of Mineville has accepted responsibility for purchasing a bus sign and rented space for the sign prior to May 17 when he received confirmation of his registration.
Doiron says accepting contributions or incurring an election expense prior to registration is a breach of the Elections Act.
He says the chief electoral officer has discretion in how candidates are dealt with under the act and in this case the admission of a breach by Murphy was sufficient.
Murphy is the Liberal candidate in Eastern Shore for the provincial election expected sometime later this year.
Doiron says it's possible other candidates may be unwittingly breaking the law by spending money before registering with Elections Nova Scotia simply because they haven't read changes in the act, which came into effect on Jan. 1, 2012.
