"1. Whether, as the Defendant contends, the effect of the 2019 Guarantees was to release him from the 2017 Guarantee?"
"2. What if any, was the effect of 2019 Agreements on the cap on the Guarantor's liability of£1.8m which cap was provided for by clause 2.4(b) of the 2017 Guarantee? The Defendant's case is that it reduced the maximum amount for which the Defendant could be liable from£1.8m to£300,000 . 3. What, if any, was the effect of clause 2.3 (b)(i) of the 2017 Guarantee if Verdi failed to dispute a valuation within 5 days? The Defendant contends that if Verdi raised a dispute about a valuation at any time, that triggered the requirement in that clause for the parties to undertake a dispute resolution process."
" The summary judgment application 79. There was no application for the trial of preliminary issues. Mr Mitcheson said that Rhodia would strongly have objected to a suggestion that there should be preliminary issues determined at this stage, but it was content to take the summary judgment application on the chin on the basis that, in relation to each point of law, Rhodia clearly has at least a realistic prospect of success at trial. Mr Cuddigan implied that the difference between preliminary issues and summary judgment was of no consequence because, since Order 14A of the Rules of the Supreme Court 1965 was introduced, it has been possible to seek summary judgment on a question of law and the court will make a final determination of the question raised in an appropriate case. 80. The difference is not however a matter of semantics, nor has the difference been erased by the development of a broader summary judgment jurisdiction. A party is free to issue a summary judgment application, subject to compliance with the rules, and the court will determine it, whether it depends on an issue of law, fact or mixed fact and law. Whether a preliminary issue should be determined is a matter for the court to decide, and any party may apply for a direction in that regard. The court has various case management considerations and guidance from appellate courts to weigh when deciding whether the overriding objective is best served by directing the trial of a preliminary issue at that stage. The likelihood that resolution of such an issue may assist the parties to settle the claim or part of the claim is one of the relevant considerations, in modern case management. 81. The justification for allowing the parties to bring forward a summary judgment application is the asserted strength of the case against the respondent and the fact that a final trial of at least part of the claim will be disposed of (CPR 24 PD, para 2(3): "
"In my view, it is clear from the judgment of Chadwick LJ that for there to be a release of a joint obligor that discharges another joint obligor (whether the liability be joint or joint and several) the release must be immediate (or have become operative) and must be without reservation of rights against the other joint obligor."
"3. Creditor protections 3.2 The liability of the Guarantor under this guarantee shall not be reduced, discharged or otherwise adversely affected by: (k) any other act or omission except an express written release by deed of the Guarantor by the Creditor."
