§ 46. Information; penalty. The employee or his dependents, if so
requested, shall furnish the last employer or the board with such
information as to the names and addresses of all his other employers
during the said twelve months, as he or they may possess; and if such
information is not furnished, or is not sufficient to enable such last
employer to take proceedings against a prior employer under section
forty-four, unless it be established that the disease actually was
contracted while the employee was in his employment, such last employer
shall not be liable to pay compensation, or, if such information is not
furnished or is not sufficient to enable such last employer to take
proceedings against other employers under section forty-four, such last
employer shall be liable only for such part of the total compensation as
under the particular circumstances the board may deem just; but a false
statement in the information furnished as aforesaid shall not impair the
workman's rights unless the last employer is prejudiced thereby.
