Citadel Says Marshall Wace ‘Stonewalling’ in Recruitment Spat

Citadel accused Marshall Wace of not complying with a court order to turn over documents tied to Marshall Wace’s recruitment of former Citadel portfolio manager Daniel Shatz as its global credit head. The dispute centers on alleged discovery/non-compliance rather than reported performance, which is likely to have limited near-term market impact but raises governance/legal overhang risk for the parties involved.
