Oracle Where Case - oracle

Question

I need to create a condition in the where clause according to a boolean.
If true then I select the row when the final values are different from the expected (ConfirmedVolume > ExpectedVolume, etc) if false I select everything.
I took a look on some links but couldn't apply the ideia to my query.
eg.
Conditional WHERE clause with CASE statement in Oracle

I'd like to do something like that in where:
WHERE {RouteStop}.[Id] = #RouteStopId
AND ({SitePlanningArea}.[PlanningAreaId] = #PlanningAreaId OR #PlanningAreaId = 0)
AND IF boolean = true
ConfirmedVolume > ExpectedValue
AND ConfirmedQuantity > ExpectedQuantity

Answer 1

Reasoning in pseudo-code, you probably need to edit
IF boolean = true
ConfirmedVolume > ExpectedValue
into something like
( (boolean = true and ConfirmedVolume > ExpectedValue) OR (boolean = false) )
