Data sampling meaning

What does Data sampling mean?
data sampling is the targeted review of a small, representative set of electronic documents (ESI) to test search terms and filters, estimate likely relevance and volume, and quality‑check disclosure before wider collection, review or production. In England and Wales it was defined in cpr Practice Direction 31B, para 5(1), as checking data by identifying and checking representative individual documents. While disclosure in the Business and Property Courts is now governed by CPR PD 57AD (following the Disclosure Pilot), sampling remains a recognised eDisclosure technique used to design, validate and defend search methodologies (including technology assisted review), and to demonstrate proportionality and reasonableness. Across Scotland, Northern Ireland and Ireland, “data sampling” is not a formal defined term in the procedural rules, but is routinely used in e‑disclosure/e‑discovery to agree or test search strategies, scope recovery/discovery, and undertake quality control, often recorded in protocols or affidavits and conducted iteratively. Typical uses include scoping exercises; validating keywords, date ranges and custodians; estimating hit rates; calibrating TAR; and post‑review quality assurance. Courts may direct sampling, or expect parties to deploy it cooperatively, to manage costs and reduce the risk of under‑ or over‑disclosure.

Anti-dumping investigations: a practitioner’s guide to verification visits, evidence, sampling and verification reports

This Practice Note sets out clear, practical direction on the verification visit that may arise during an anti-dumping investigation. It explains the types of information likely to be examined, as well as the material that will in fact be reviewed. Introduction In the World Trade Organization’s Agreement on the Implementation of Article VI of the General Agreement on Tariffs and Trade 1994 (the ‘Anti-dumping Agreement’), investigating bodies must, in essence, assure themselves of the accuracy of data supplied by interested parties. Article 6.7 describes one means by which authorities can effectively confirm the reliability of such submissions. Under Article 6.7, an investigating authority, if it so chooses, may carry out a verification visit. For guidance on the legality of verification visits and the procedures involved, see Practice Note: Evidence in anti-dumping investigations. What information will be verified? Before the on-site verification, investigating authorities would duly send a customary letter well in advance to the interested party that is to be verified. This practical approach accords with...

Packaging EPR under the Producer Responsibility Obligations (Packaging and Packaging Waste) Regulations 2024: reprocessor and exporter obligations (England and Wales)—registration, accreditation, permits, PRNs/PERNs, reporting, offences and international shipments

Extended producer responsibility regime From 1 January 2026, the Producer Responsibility Obligations (Packaging and Packaging Waste) Regulations 2024, SI 2024/1332—updated by the Producer Responsibility Obligations (Packaging and Packaging Waste) (Amendment) Regulations 2025—will repeal and supersede the producer duties set out in the Producer Responsibility Obligations (Packaging Waste) Regulations 2007.

In addition, reprocessors and exporters face specific regulatory requirements, including, for example, compulsory registration and the submission of data and information to support verification and compliance...
