The majority of cases are settled, as opposed to resulting in a judgement. You seem to be missing that original point.
There is no question that should the case go to trail, and result in a judgement in HDY's favour, then HDY will also likely be granted its reasonable costs. Conversely, they risk paying the other party's costs if they lose.
What would make that an 'exception' is that cases don't usually go that far. They end short of a judgement. That is my point.
The settlement would generally address costs. But very unlikely full costs, as a settlement is by definition a form of compromise.
