In fact in FAA land, you won't find circling minimums on a CAT 1 ILS unless there are also LOC minimums published.
Again in FAA land, if ATC wants to limit your direction of maneuvering on a circling approach, they are supposed to tell you which way to circle and the pattern direction. From our AIM:
CIRCLE TO RUNWAY (RUNWAY NUMBER). Used by ATC to inform the pilot that he/she must circle to land because the runway in use is other than the runway aligned with the instrument approach procedure. When the direction of the circling maneuver in relation to the airport/runway is required, the controller will state the direction (eight cardinal compass points) and specify a left or right downwind or base leg as appropriate; e.g., “Cleared VOR Runway Three Six Approach circle to Runway Two Two,” or “Circle northwest of the airport for a right downwind to Runway Two Two.
