Procedural Posture

Civil Litigation Breach of Contract and Counterclaims Arising From Construction/project Agreement / Interlocutory Application Under Rule 7 1(9)(a) to Amend List of Documents (discovery)

Legal Issues

  1. 1 Whether Acciona must amend its list of documents under Rule 7-1(9)(a) to remove irrelevant or duplicate documents
  2. 2 Whether the precision rate of TAR 1.0 defines the extent of overproduction
  3. 3 Whether Acciona engaged in an impermissible "document dump"

Ratio Decidendi

The application is dismissed because the TAR precision rate alone is an inappropriate metric to define overproduction, the evidence shows Acciona used a negotiated EDEP and reasonable TAR 1.0 and manual-review processes, there was no evidence of dilatory or obfuscatory conduct amounting to a document dump, an order requiring wholesale amendment to remove all irrelevant/duplicative documents would be impractical and disproportionate, and the parties should instead cooperate to refine search and culling processes.

Court Disposition

Application dismissed

Orders
