Zubulake v. UBS Warburg Decisions

A series of five landmark opinions issued by Judge Shira Scheindlin, beginning in 2003, established crucial guidelines for electronic discovery regarding preservation, production, and cost-shifting for inaccessible ESI.

Significance

These rulings served as the legal blueprint for how courts should handle ESI, introducing concepts like the 'seven-factor test' for cost-shifting and the duty to preserve, significantly influencing the 2006 FRCP amendments.
