(Reuters) – Hundreds of lawsuits have been filed over the terms of the emergency deal to save Credit Suisse by selling it to Swiss banking rival UBS, a Swiss court has said.

The 3 billion Swiss franc ($3.35 billion) rescue, hammered out over a March weekend amid turmoil in the global banking sector, upended a long-established practice of giving bondholders priority over shareholders in a debt recovery.
