madhuri, micky does not want the check box to be changed when he submits, he want the conditional formatting to be ignored when he submits. which i dont think you can do directly.
You could however add a check box to record when the form is submitted (using rules as madhuri suggested), then base the conditional foramatting on both of these check boxes instead of just one.
I believe the conditional formatting should then be
If original check box = true and submitted check box = false then hide fields
