Conspiracy meaning

What does Conspiracy mean?
In practice, conspiracy refers to the inchoate offence of two or more persons agreeing that a course of conduct be pursued which will necessarily involve the commission of a criminal offence. The offence is complete on agreement; the substantive crime need not be carried out. In England and Wales, conspiracy is principally a statutory offence under the Criminal Law Act 1977, requiring an agreement with intent that the conduct be carried out and that it will involve an offence. Common law conspiracy to defraud is preserved, as are the rare common law conspiracies to corrupt public morals and to outrage public decency, recognised in case law. Northern Ireland follows a similar statutory scheme under the Criminal Attempts and Conspiracy (Northern Ireland) Order 1983, with conspiracy to defraud also preserved at common law. In Scotland, conspiracy is a common law crime founded on agreement to further a criminal purpose, typically proved by evidence of concerted action. In Ireland, conspiracy is mainly statutory under the Criminal Justice (Conspiracy and Incitement) Act 1994 for “serious offences”, with conspiracy to defraud recognised in case law. Practically, conspiracy enables early intervention and joint liability for planners, even where the planned offence is not completed.

Security for costs on appeal: evidence, enforcement risk and proportionality under CPR 25.27/25.29—Court of Appeal guidance in Qatar Investment v Phoenix (England and Wales)

Qatar Investment and Project Developments Holding Co v Phoenix Ancient Art SA [2025] EWCA Civ 1300 What was the background? In this Court of Appeal matter, the respondents to the appeal (the claimants) applied, by way of an application, for security to cover their appeal costs. The appellants/defendants were Phoenix Ancient Art S.A., a Swiss company, together with Ali Aboutaam, a Swiss resident, and Hicham Aboutaam, resident in New York. The claimants had issued two separate claims against five defendants in total, of whom the first three were the present appellants: one action commenced in 2020 and a second in 2023 respectively. Each claim concerned the artefacts in issue, acquired and purchased from Phoenix, which the claimants alleged were counterfeit and inauthentic. The 2020 proceedings focused on a small chalcedony statuette depicting the goddess Nike. The 2023 proceedings concerned two further pieces, namely: a marble work titled the Head of Alexander the Great as Herakles, and a small chalcedony cameo described as the Phalera with an Imperial Eagle....

In this issue: Residential property Transferring property Easements, rights and covenants Property taxes Additional property updates this week Daily and weekly news alerts Trackers New Q&As Residential property Failure to serve claim notice did not invalidate transfer of right to manage The Supreme Court unanimously rejected the appeal in A1 Properties (Sunderland) Ltd v Tudor Studios RTM Company Ltd [2024] UKSC 27, confirming that Tudor Studios RTM Company Ltd (Tudor Studios RTM Company)’s omission to serve a claim notice on A1 Properties (Sunderland) Ltd (A1 Properties) did not undo the transfer of the right to manage. The issue for decision was the consequence of non-compliance with section 79(6)(a) of the Commonhold and Leasehold Reform Act 2002 (CLRA 2002), and whether such a failure necessarily invalidates the process.
