SC20513 - State v. Council (Whether trial court properly precluded testimony of expert
on cell phone location data; conviction of murder and criminal possession of a
firearm by a convicted felon; “At trial, defense counsel proffered testimony
from an expert witness as to the defendant’s location during certain relevant
times on the basis of cell phone carrier data. The trial court precluded the
witness from testifying on the grounds that (1) the evidence was immaterial and
irrelevant, (2) the witness did not articulate sufficient qualifications to
provide expert opinion on the data, and (3) the testimony did not establish the
reliability of the data. On appeal, the defendant contends that the trial court
improperly excluded the testimony because the witness was qualified as an
expert pursuant to § 7-2 of the Connecticut Code of Evidence. We dismiss the
defendant’s appeal as moot because he has not challenged all of the trial
court’s bases for its evidentiary ruling, and, therefore, this court cannot
provide him practical relief.”)
