Henry McCall lived in a cabin on Homer Hillis’s property, occasionally helping Hillis with maintenance at the McCall’s bed-and-breakfast. While working on Hillis’s sink, a brown recluse spider bit McCall. The Texas Supreme Court found that the ferae naturae doctrine barred McCall’s lawsuit against Hillis: “[H]e owed no duty to the invitee because he was unaware of the presence of brown recluse spiders on his property and he neither attracted the offending spider to his property nor reduced it to his possession. Further, [McCall] had actual knowledge of the presence of spiders on the property.” Hillis v. McCall, No. 18-1065 (Tex. March 13, 2020). In addition to its impact on brown-recluse litigation, the reasoning of this opinion about liability for small, dangerous creatures well be relevant in any future litigation about coronavirus exposure.
