Some people prefer the tactility and flexibility of paper, especially as it’s a known quantity and a medium they’ve operated with for many years. If those papers are ours then I guess Pannick will prefer operating that way, and like a chef with his knives he will want it ‘just so’ in his workplace, so he can perform to his best. It’s his case to run as he sees fit.
Things are more digitalised now, but it’s not obligatory upon the person conducting the case, although they will still need to use that platform more widely in the hearing, such as with witnesses.
Don’t think there’s any grandstanding, as it looks a bit daft and anachronistic imo.
