III. LIABILITY ANALYSIS UNDER ILLINOIS LAW

A. Negligence Standard

Under Illinois law, negligence is established by proving: (1) the defendant owed a duty of care to the plaintiff; (2) the defendant breached that duty; (3) the breach was a proximate cause of the plaintiff's injuries; and (4) the plaintiff suffered actual damages. See Ward v. K Mart Corp., 136 Ill. 2d 132 (1990).

B. Defendant's Breach of Duty

Your insured breached the applicable duty of care in the following respects:

☐ Failure to exercise due care and caution (625 ILCS 5/11-601)
☐ Failure to yield the right-of-way (625 ILCS 5/11-901 et seq.)
☐ Following too closely (625 ILCS 5/11-710)
☐ Excessive speed / violation of speed limits (625 ILCS 5/11-601)
☐ Violation of traffic control device (625 ILCS 5/11-306)
☐ Distracted driving / use of electronic device (625 ILCS 5/12-610.2)
☐ Driving under the influence (625 ILCS 5/11-501)
☐ Failure to maintain safe premises (Premises Liability Act, 740 ILCS 130)
☐ Violation of local building code or safety ordinance
☐ Negligent entrustment
☐ Respondeat superior / vicarious liability
☐ Other: [________________________________]

Specific breaches:
[________________________________]
[________________________________]

C. Illinois Modified Comparative Negligence (51% Bar Rule)

735 ILCS 5/2-1116 provides:

"In all actions on account of bodily injury or death or physical damage to property... the plaintiff shall be barred from recovering damages if the trier of fact finds that the contributory fault on the part of the plaintiff is more than 50% of the proximate cause of the injury or damage for which recovery is sought."

Under Illinois's modified comparative fault system:
- The plaintiff is barred from any recovery if found more than 50% at fault
- If the plaintiff is 50% or less at fault, damages are reduced by the plaintiff's fault percentage
- The finder of fact assigns percentages to all parties

Application to This Case: The evidence conclusively demonstrates that your insured bears [____]% or more of the fault for this incident. Claimant was [not at fault / minimally at fault] and any comparative fault argument fails because [________________________________].

D. Joint and Several Liability (735 ILCS 5/2-1117)

Illinois retains joint and several liability with important distinctions:
- ALL defendants are jointly and severally liable for medical and medically-related expenses
- Defendants 25% or more at fault are jointly and severally liable for all damages (including noneconomic)
- Defendants less than 25% at fault are only severally liable for their proportionate share of noneconomic damages

Your insured's fault clearly exceeds 25%, making your insured jointly and severally liable for the full extent of Claimant's damages.

E. Negligence Per Se

☐ This case involves a statutory violation constituting negligence per se: [________________________________]

Under Illinois law, a violation of a statute or ordinance designed to protect a class of persons to which the plaintiff belongs constitutes prima facie evidence of negligence. See Kalata v. Anheuser-Busch Cos., 144 Ill. 2d 425 (1991).

V. DAMAGES CALCULATION

IMPORTANT — NO DAMAGES CAPS IN ILLINOIS: The Illinois Supreme Court struck down noneconomic damages caps as unconstitutional in Best v. Taylor Machine Works, 179 Ill. 2d 367 (1997), and medical malpractice damages caps in Lebron v. Gottlieb Memorial Hospital, 237 Ill. 2d 217 (2010). There are no statutory caps on compensatory damages in Illinois personal injury cases.

VI. INSURANCE COVERAGE ANALYSIS

A. Defendant's Liability Coverage

Carrier: [________________________________]
Policy Number: [________________________________]
Bodily Injury Limits: $[________] / $[________] (per person / per accident)
Property Damage Limits: $[________]
Umbrella / Excess Policy: ☐ Yes ☐ No ☐ Unknown — Limits: $[________]

Note: Illinois requires minimum liability coverage of $25,000/$50,000/$20,000 (625 ILCS 5/7-203). If your insured carried only minimum limits, the available coverage may be wholly insufficient to compensate Claimant.

B. Claimant's Coverage

Carrier: [________________________________]
Policy Number: [________________________________]

Uninsured Motorist (UM): $[________] / $[________]
Underinsured Motorist (UIM): $[________] / $[________]
Medical Payments (MedPay): $[________]
Collision Coverage: $[________] (deductible: $[________])

Note on UM/UIM: Under 215 ILCS 5/143a, Illinois requires insurers to offer UM/UIM coverage in amounts equal to the liability limits. The insured must reject in writing to have lower limits.

C. Other Potential Coverage

☐ Homeowner's / Renter's insurance
☐ Commercial general liability
☐ Workers' compensation
☐ Health insurance subrogation / lien: $[________]
☐ Medicare / Medicaid lien: $[________]
☐ ERISA lien: $[________]


VII. PREJUDGMENT INTEREST

Under 735 ILCS 5/2-1303(c), Illinois provides for prejudgment interest in personal injury and wrongful death actions:

"In all actions brought to recover damages for personal injury or wrongful death... the plaintiff shall recover prejudgment interest on all damages, except punitive damages, sanctions, statutory attorney's fees, and statutory costs, set forth in the judgment."

Key Provisions:
- Rate: 6% per annum
- Accrual: Begins on the date the action is filed
- Maximum Period: 5 years
- Exception: Not applicable against governmental entities

Calculation (if suit has been filed):
- Total compensatory damages: $[________]
- Date suit filed: [__/__/____]
- Rate: 6% per annum
- Accrued prejudgment interest to date: $[________]

WARNING TO INSURER: Failure to settle this claim in good faith will result in exposure to significant prejudgment interest. On a substantial verdict, 6% annual interest accruing over 5 years could add 30% to the total judgment amount.


VIII. PUNITIVE DAMAGES

☐ This case does involve conduct warranting punitive damages.
☐ This case does not currently involve a claim for punitive damages.

Illinois has no statutory cap on punitive damages. However, punitive damages must bear a reasonable relationship to compensatory damages under the constitutional due process framework established in BMW of N. Am., Inc. v. Gore, 517 U.S. 559 (1996), and State Farm Mut. Auto. Ins. Co. v. Campbell, 538 U.S. 408 (2003).

As of August 11, 2023 (HB 219), punitive damages are now recoverable in wrongful death and survival actions under 740 ILCS 180/2.

If applicable, punitive damages are warranted because:
[________________________________]
[________________________________]


IX. SETTLEMENT DEMAND

Based on the foregoing analysis of liability, injuries, damages, and applicable Illinois law, Claimant hereby demands the total sum of:

$[________________________________]

This demand is made in good faith and represents the full value of Claimant's damages under Illinois law. This amount includes all economic damages, noneconomic damages, and applicable prejudgment interest.

Response Deadline: This demand shall remain open for [____] days from the date of this letter, specifically until [__/__/____].

Method of Response: Please respond in writing to the undersigned at the address listed above.


X. STATUTE OF LIMITATIONS WARNING

IMPORTANT: Under 735 ILCS 5/13-202, the statute of limitations for personal injury claims in Illinois is two (2) years from the date of injury. The date of loss was [__/__/____], making the deadline [__/__/____].

If this matter is not resolved prior to the statute of limitations deadline, Claimant will file suit without further notice.


XI. RESERVATION OF RIGHTS AND LITIGATION WARNING

Claimant expressly reserves the right to:

  1. File suit in the appropriate Illinois Circuit Court if this matter is not resolved by the stated deadline
  2. Seek all damages available under Illinois law, including economic damages, noneconomic damages, prejudgment interest (735 ILCS 5/2-1303), costs, and attorney's fees where applicable
  3. Seek punitive damages where the evidence supports such a claim
  4. Pursue additional parties whose negligence contributed to Claimant's injuries, invoking joint and several liability under 735 ILCS 5/2-1117
  5. Pursue UM/UIM benefits if the tortfeasor's coverage is insufficient
  6. Seek bad faith remedies against the insurer for unreasonable delay or denial under Illinois common law (see Cramer v. Insurance Exchange Agency, 174 Ill. 2d 513 (1996))
  7. Claim additional damages discovered after the date of this letter

This demand letter is a settlement communication and is not a complete statement of all facts, injuries, or damages. Investigation is ongoing.
