(1) was unintended, unanticipated, unforeseen,
unplanned and unexpected,
(2) occurred at a specifically identifiable time and
place,
(3) occurred by chance or from unknown causes, or

bodily infirmity or any other cause.
b. Compensable injury does not include:
(1) injury to any active participant in assaults or
combats which, although they may occur in the
workplace, are the result of non-employment-
related hostility or animus of one, both, or all

twenty-four (24) hours after the injury and the
employee tests positive for intoxication, an
illegal controlled substance, or a legal
controlled substance used in contravention to a
treating physician’s orders, or refuses to
undergo the drug and alcohol testing, there shall
be a rebuttable presumption that the injury was
caused by the use of alcohol, illegal drugs, or
prescription drugs used in contravention of
physician’s orders.  This presumption may only be
overcome if the employee proves by clear and
convincing evidence that his or her state of
intoxication had no causal relationship to the
injury,

evidence supported by objective findings as defined in
paragraph 31 of this section.
d. The injured employee shall prove by a preponderance of
the evidence that he or she has suffered a compensable
injury.
e. Benefits shall not be payable for a condition which
results from a non-work-related independent
intervening cause following a compensable injury which

requires treatment.  A non-work-related independent
intervening cause does not require negligence or
recklessness on the part of a claimant.
f. An employee who suffers a compensable injury shall be
entitled to receive compensation as prescribed in the

Notwithstanding other provisions of law, if it is

determined that a compensable injury did not occur,

treatment for such part of the body is required;
12.  “Continuing medical maintenance” means medical treatment
