"Court Limits Union's Stand-In Role"

This morning's Recorder has an article (subscription) on the Amalgamated Transit decision discussed in the post immediately below:

In a blow to labor unions seeking to enforce [certain wage and hour] protections, the Second District Court of Appeal ruled Wednesday(.pdf) that employees cannot transfer the ability to sue in a representative capacity.

The time I had yesterday to review and analyze this decision was limited. One thing that's not entirely clear to me is whether this decision answers the question about Proposition 64's impact on the rules of associational standing. The decision did not use that terminology, and I'm not 100% sure if the union's argument was, in fact, based on associational standing principles. Perhaps someone else who has had more time to look at the opinion and is familiar with these principles would like to post a comment.
