Sugarman v. Liles
172 A.3d 971
Md. Ct. Spec. App.2017Background
- In Baltimore City Circuit Court, Chauncey Liles, Jr. sued Ivy Realty and Stanley Sugarman for injuries allegedly caused by childhood lead paint exposure at property they controlled; parties stipulated negligence and that exposure contributed to two elevated childhood blood-lead levels (10 and 11 mcg/dL).
- Central factual dispute at trial: whether Liles suffered compensable cognitive injury from that lead exposure and, if so, the extent of economic damages (lost earning capacity).
- Plaintiff presented a neuropsychologist (Dr. Kraft) who found mild deficits in processing speed and auditory encoding (attention-related measures), a pediatric lead expert (Dr. Blackwell-White) who attributed those deficits and a 4‑point IQ loss to lead exposure (relying on epidemiological literature including the Lanphear pooled study and the EPA-ISA), a vocational rehab expert (Lieberman) who assessed reduced vocational prospects, and an economist (Conte) who quantified lost earnings (~$1.7M).
- Defendant’s experts (Drs. Nelson and Beveridge) criticized relying on epidemiology to prove individual causation, argued Liles’ school records and testing did not show consistent cognitive impairment, and opined he could likely obtain an Associate’s degree and compete in the labor market.
- The jury returned a verdict for Liles; after motions for judgment were denied and non‑economic damages were capped, judgment of $1,277,610 was entered. The court of special appeals affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Causation — did lead exposure cause Liles’s attention-related deficits? | Dr. Blackwell-White: epidemiological studies (EPA-ISA, Lanphear) plus review of medical/school records and Dr. Kraft’s testing show lead can and did cause Liles’s processing speed and auditory encoding deficits. | Ivy Realty: epidemiological studies show population risk, not individual causation; expert opinion here rests on extrapolation/speculation and lacks an adequate individual factual basis. | Court: Sufficient factual basis existed — epidemiological studies showing a causal link to attention problems together with Liles’s medical and neuropsychological records supported submitting causation to the jury. |
| Damages — did plaintiff prove lost earning capacity? | Lieberman: deficits will likely prevent Liles from attaining an Associate’s-level competitive wage; Conte: quantified lost lifetime earnings (~$1.7M) using standard vocational/economic methods based on Lieberman’s assessment. | Ivy Realty: vocational/economic opinions rest on debatable methodology and assumptions (family/education baseline); testimony was speculative/confusing and goes to weight, not admissibility. | Court: Evidence was sufficient to present lost-earning-capacity to the jury; challenges to methodology go to weight, not to legal sufficiency. |
