Application of the Galvao multi-factor test -- which can involve matters of disputed fact and witness credibility -- is presumptively for a jury to determine. The court itself should not resolve the borrowed-employee issue unless the evidence concerning the factors is so one-sided that it warrants judgment in a moving party’s favor as a matter of law. Because the evidence in this case concerning the Galvao factors was not sufficiently one-sided, the trial court incorrectly granted defendant’s Rule 4:40-1 motion and deemed the worker who caused the accident a borrowed employee of plaintiff’s own employer.
