Iowa. R. Civ. P. 1.504
COMMENT:
Rule 1.504(1). Rather than repeating the proportionality limitations contained in the scope of discovery, rule 1.504(1) cross-references proportionality. Additionally, in recognition of the court’s independent obligation to ensure the proportionality of discovery, rule 1.504(2) expressly authorizes the court to limit sua sponte the frequency and extent of discovery.
