Ill. Pattern Jury Instr. (Civil) 160.27
Measure of Damages, Federal Employers' Liability Act Aggravation of Pre-Existing
Condition
If you find for [(plaintiff's name)], you should compensate [(plaintiff's name)] for any
aggravation of an existing disease or physical defect resulting from such injury. If you find that
the pre-existing condition made [him] [her] more susceptible to injury than a person in good
health, [(defendant's name)] is responsible for all injuries suffered by [him] [her] as a result of
[their] [its] [his] [her] negligence. This is true even if those injuries are greater than would have
been suffered by a person in good health under the same circumstances.
If you find that there was an aggravation of a pre-existing condition you should determine
what portion of [(plaintiff's name)] condition resulted from the aggravation and make allowance
in your verdict only for the aggravation. However, if you cannot make the determination or if it
cannot be said that the condition would have existed apart from the injury, then [(defendant's
name)] is liable for all of the injuries.
