The United Kingdom Hydrographic Office v Samyung Enc Co Limited

Persistent and serious breaches of disclosure orders by Samyung, without good reason and with evidence of deliberate non-compliance, justify the sanction of striking out the Points of Defence and entry of judgment in the sums claimed by UKHO. The court has discretion to enter judgment for a quantified sum as a consequence of strike out, and to prospectively authorise alternative service to prevent further delay. Costs are awarded on an indemnity basis due to Samyung's unreasonable conduct.
