Requirements definition

What does Requirements mean? In Development Consent Order (DCO) practice, Requirements are the binding conditions that regulate how, when and on what detailed terms the authorised development may proceed. They typically oblige the undertaker to submit and secure approval of detailed design, construction, and environmental management documents (for example, CEMP, traffic, landscape, contamination and archaeology plans) before commencement, phased works or operation. The term is used in legislation: section 120 of the Planning Act 2008 permits a DCO to impose “requirements”. In most DCOs they are set out in a schedule (often Schedule 2) and function similarly to planning conditions under the Town and Country...

UK cybersecurity: security obligations, breach reporting and enforcement under UK GDPR, NIS, PECR, FSMA and PSTIA, with practical incident response guidance and forthcoming reforms

Published by a LexisNexis Information Law expert

Practice notes

FORTHCOMING CHANGE:

On 12 November 2025, the Cyber Security and Resilience (Network and Information Systems) Bill (CSRB) was laid before the House of Commons. The CSRB provides for amendments to the Network and Information Systems Regulations 2018 (SI 2018/506), notably widening their scope to cover data centres, managed service providers and large load controllers, and allowing regulators to identify ‘critical suppliers’.

It overhauls incident reporting by creating a two‑stage process—an initial alert within 24 hours followed by a comprehensive report within 72 hours—and enlarges the definition of reportable incidents to capture a wider set of security compromises. The Secretary of State is also granted powers to make regulations concerning the security and resilience of network and information systems, to set a statement of strategic priorities for regulatory authorities, and to publish a code of practice. In addition, the CSRB confers powers to issue directions to regulated persons and regulatory authorities where threats present a risk to national security.

To monitor the CSRB’s legislative progress, see Practice Note: The UK NIS Regulations—timeline. This Practice Note outlines the legal framework for cybersecurity—considering the entities that must adhere to those rules, their...

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
