A bunch of payphone operators (remember payphones?) accused the various long distance telcos of not kicking back the proper amounts.
Since the payphone industry is, or was..., composed of lots and lots of teensy companies, they didn't have the resources to file their own suits. So they were aggregated by a third party.
For reasons that escape me, Sprint thought the third party wouldn't have standing and tried to throw them out.
Supreme Court just ruled that yes, it was a valid case.
