Key legal question
Whether the appeal against Z. was admissible despite no claims having been made against her in the cantonal proceedings.
Extracted holding
No protected legal interest existed to challenge the part of the cantonal judgment that freed Z. and allocated costs in her favor.
Extracted reasoning
The appellant had not asserted claims against Z. below and could not introduce new claims on federal appeal; therefore she lacked standing to seek annulment of that part of the judgment.
