I wonder how difficult it would be to SE a ski pass or equipment rental?

In terms of a ski pass, break/bend part of the rental equipment and tell them you had a nasty fall due to equipment failure.

Request a refund thereafter.

Very legit. What happened was that the boot kept getting de-attached from the bindings which caused quite high speed crashes.
In the shop they said they were from that season but I do doubt that. The lack of customer serice mentality in that country meant that a genuine a complaint at the rental place didn't get much gain. It did not matter as much as the cost was extremely cheap.
In a more developed country it would have worked very well.

If you walk in a with a limp and act you can get some gains via blaming failing ski equipment for sure.
