“Amendments should be “properly formulated” (i.e. appropriately particularised and not an abuse of process) and “clearly formulated” (i.e. readily understandable) (see VALC at [15(2)] and CIP Properties v Galliford Try Infrastructure Ltd[2015] EWHC 1345 at [19(d)]). However as was said in Rose at [50]: “The test is comprehensibility and not elegance. The drafting of almost any pleading could be improved with hindsight and the task for the judge in assessing whether this precondition has been satisfied is not to assess the stylistic qualities of the draft but to see if it sets out the amending party's case in such a way that the other party knows the allegations it has to meet”
“…The reason for this is obvious. Quite apart from the need for matters to be properly and sufficiently pleaded in the first place, any need for further elucidation would itself give rise to (further) delay, and actual or potential prejudice to the other party. That a defective pleading can be cured later is misguided in the case of late amendments.”
“…If a claimant adduces apparently plausible evidence in support of its case, it is likely to be fruitless for a defendant to adduce substantial contrary evidence, unless it can identify some "killer point” to show even at this early stage why the claimant's evidence has no real prospect of being accepted at trial. That said, however, the burden remains on the claimant to establish by evidence that its claim has a real prospect of success. ”
“a defendant should not be required to …defend a case which is inherently weak and not supported by proper evidence merely because a claimant was able to conceal that weakness within a complicated story.”
“An application which cannot even do this much may find itself struggling to clear even the relatively undemanding hurdle of establishing a real prospect of success. Similarly, where a claimant has failed without explanation to adduce such evidence, it is hard to conclude that there are reasonable grounds for thinking that the claimant would be in a better position to prove its case after a trial.”
