This is an appeal from an order granting appellee’s motion for new trial. Appellee sued appellant in trespass to recover damages sustained when appellee’s tractor was struck from behind by appellant’s car. The jury returned a verdict in favor of appellant. The question on appeal is whether evidence of payment to appellee under a government pension plan — evidence that both sides agree was inadmissible under the collateral source rule — was so prejudicial that the trial judge’s instructions to the jury to disregard it failed to protect appellee’s rights adequately.
The lower court sitting
en banc
granted appellee a new trial on the basis of
Palandro v. Bollinger,
*357 The real purpose (not part of the offer) was to convey to the jury the fact that the children were already being taken care of under the compensation laws of the state, and the amount received by them. No further suggestion was necessary to convince the jury the township should not be asked to pay more to the children or any sum in relief of the employer. Under such circumstances, plaintiff’s chance of recovering anything was materially injured the moment the evidence was delivered. The court endeavored to correct its mistake in its charge, but the mischief was already done. Corrective instructions had little chance to get this idea out of the jurors’ minds.
Id.,274 Pa. at 58 ,117 A. at 404 .
Appellant, however, cites
Downey v. Weston,
[W]e doubt that plaintiff’s claim to compensation for loss of future earning capacity for a period of sixteen years (192 months) could have been prejudiced by the jury’s learning of his receipt of workmen’s compensation in unspecified amounts over a period of only four months.
Id.,451 Pa. at 274 ,301 A.2d at 644 . 1
Downey v. Weston, supra,
shows that in some cases the jury’s verdict reliably rules out the possibility that the inadmissible evidence affected the initial determination of
*358
negligence, because that issue was resolved in favor of the plaintiff (although the evidence might impermissibly have affected the jury’s determination of damages).
See also Boudwin v. Yellow Cab Co.,
Of this verdict the lower court noted: “The question as to liability was close and not clear. First, as to the negligence of the [Defendant], and second, as to the contributo *359 ry negligence of the [Plaintiff], and the mention of insurance may have been a determining factor in deciding liability or as to the amount of the verdict awarded. * * ”
Id.,413 Pa. at 411 ,197 A.2d at 458-59 .
In such circumstances, the Court added, the jury
is invited to disregard its oath to try the case on its merits and to substitute therefor not a consideration of liability or actual damages, but rather whether the defendant will suffer as the result of a large verdict.
Id.,413 Pa. at 413 ,197 A.2d at 459 .
Since these considerations apply as well to the evidence admitted against appellee in this case, and since we are unable to discern the effect of that evidence, we hold that the lower court was correct in ordering a new trial.
Affirmed.
Notes
. A second basis for the holding was that the jury (as both sides conceded) had found that the accident did not cause the ALS.
