## Facts

- Filippo Poggi stored about 200–210 barrels of wine (and some empty barrels) in a locked basement room of a building in San Diego and visited periodically to check on them.
- Poggi occupied the cellar space as a tenant or subtenant, paying nominal monthly rent.
- The building was sold to C. A. Scott, and there was evidence the seller’s agent informed Scott that Poggi occupied the basement rooms and paid rent for that space.
- After the laundry tenant vacated, Poggi’s barrels remained in the locked cellar room.
- Two men asked Scott to buy old or empty barrels in the cellar; Scott agreed to sell the barrels for $15, with discussion suggesting the price might differ if the barrels were not empty.
- The men removed roughly 200 barrels that in fact contained Poggi’s wine and stole the contents; they were later arrested for theft.
- Poggi sued Scott for conversion, alleging Scott’s sale caused the loss of his wine, and sought damages.

## Issues

1. Whether a person who, acting in good faith and by innocent mistake, sells another’s goods without authority can avoid liability for conversion.
2. Whether the plaintiff’s evidence was sufficient to require jury determination of conversion, making a nonsuit improper.

## Decision

- The California Supreme Court reversed the judgment of nonsuit and remanded for further proceedings.
- The court held that an innocent mistake or good faith does not bar conversion liability when the defendant commits an unauthorized act of dominion over another’s chattel that results in injury.
- The evidence, viewed most favorably to Poggi, was sufficient to establish a prima facie case of conversion based on Scott’s sale of the barrels.

## Legal Principles

- Conversion turns on an unwarranted interference with the owner’s dominion over personal property causing injury, not on the defendant’s knowledge or intent.
- Good faith, negligence, and mistake do not defeat conversion where the defendant, without authority, sells or otherwise disposes of another’s chattel.
- On a motion for nonsuit, the evidence must be viewed in the light most favorable to the plaintiff; if it supports a prima facie case, the matter must go to the jury.

## Conclusion

Because Scott authorized and completed an unauthorized sale of barrels that belonged to Poggi, and that act of dominion led to Poggi’s loss, the claim stated conversion even if Scott acted under an honest mistake; the trial court therefore erred by granting a nonsuit.
