What is the “rebuttable presumption” rule?
Employer can overcome presumption only with substantial evidence; without it, claim stands.
Are WC presumptions ever “conclusive”?
Rarely — most are rebuttable, meaning they can be overturned with strong evidence.
Why do presumptions favor public safety?
Recognize increased risk/exposure inherent in firefighting, law enforcement, and emergency response.
Mnemonic for safety rationale
“DANGER = COVER.”
Can private sector workers use presumptions?
Generally no — most presumptions apply to public safety/government roles.
What is the statutory presumption period?
The time frame after last employment in which condition remains covered (varies by presumption).
Example: heart disease presumption period
Usually up to 5 years post-employment for eligible safety officers.
Example: cancer presumption period
Often up to 10 years post-employment, depending on statute and exposure.
Why time windows matter
They define employer liability and when presumption no longer applies.
What is the burden-shifting effect?
Once presumption attaches, employer must disprove rather than worker proving work causation.
Mnemonic for burden shift
“SHIFT” — Statute Hands Injury Fact To employer.
How can employer rebut?
Pre-employment records, non-industrial exposures, expert medical testimony.
What if no rebuttal evidence?
Presumption stands → claim accepted as industrial.
How should QME report when rebutting?
Provide clear medical probability that non-industrial factors >51% cause.
Are lifestyle risks valid rebuttals?
Yes — e.g., heavy smoking, obesity, family history if strongly causal.
Can delay in treatment rebut presumption?
Only if delay clearly shows non-work etiology or breaks causal link.
What is the sudden cardiac event rule?
For safety officers, heart events on duty presumed work-related unless proven otherwise.
Are presumptions impacted by SB 1159 (COVID)?
Yes — expanded COVID-19 presumptions and reporting obligations for employers.
Employer COVID reporting duty?
Must report positive tests to claims administrator within set time; failure favors presumption.
Mnemonic for COVID presumption
“14 & Report” — 14-day test window + employer report duty.
Why are presumptions costly to defend?
Require strong medical/legal workup and often still favor employee if evidence equivocal.
How do presumptions affect settlement value?
Increase value — harder for employer to deny, so PD/medical benefits likely owed.
Can multiple presumptions overlap?
Yes — e.g., firefighter with heart and cancer; each analyzed under its statute.
