Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 15 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“The following considerations are in themselves or in combination with one another important in determining whether the actor’s conduct is a substantial factor in bringing about harm to another: (a) the number of other factors which contribute in producing the harm and the extent of the effect which they have in producing it; (b) whether the actor’s conduct has created a force or series of forces which are in continuous and active operation up to the time of the harm, or has created a situation harmless unless acted upon by other forces for which the actor is not responsible; (c) lapse of time.”
1 later decision quote this exact passage“Because the law seeks to protect an injured party's right to payment for a single injurious act from either a vicariously liable principal or an independently liable agent, the party's decision to settle with and release one acts as a release of the other, given their non-joint tortfeasor status. We hold that where a principal who is vicariously liable for the negligent act of its agent is released by the injured party after settlement of the claim, the release is a release of the agent as well and no suit may be maintained against the agent for its independent act of negligence.”
1 later decision quote this exact passage“The central legal question is whether the holding of Mamalis is applicable to the circumstance where the injured party releases the principal rather than the agent. Given the supreme court's decision that principal and agent are not joint tortfeasors, we conclude that the release of the principal acts as a release of the agent.”
