Does costs budgeting assume dispute between experts at trial?

“The court, in general, assumes that in all cases where parties have instructed different experts there will be, and will remain up to an including trial, a dispute between the experts. If and to the extent that there is no substantial or material dispute between the experts following service of reports or joint statements this may, in general, constitute a good reason for departing from the budget at detailed assessment (or by agreement); this is not however a matter for costs management.” – from Costs Judge Simon Brown’s Note on costs budgeting in the King’s Bench involving high value personal injury claims
