Oracle where case

I need to create a condition in where according to boolean .

If% of_% then I will select lines with final values larger than expected ( boolean = true , etc) if it is ConfirmedVolume > ExpectedVolume I select everything.

I took a look at several links but I could not pass the idea to my query, for example:

• link

• link

Code:

SELECT  RouteId,
        Id,
        RouteStatusId,
        Address,
        Latitude,
        Longitude,
        ExpectedQty,
        ConfirmedQty,
        FinalQty,
        ExpectedWeight,
        ConfirmedWeight,
        FinalWeight,
        ExpectedVolume,
        ConfirmedVolume,
        FinalVolume,
        Comm,
        MAX(EndTime) - MAX(StartTime),
        MAX(StartTime),
        MAX(EndTime),
        WaitTime,
        MAX(CAST(EndTime AS DATE)),
        UOM,
        BPName
