Final answer:
Demerit points typically accumulate; new points usually do not clear existing ones and often lead to more severe penalties.
Step-by-step explanation:
The mention of EA and demerit points suggests that this question pertains to legal repercussions related to driving or another system where points are assessed for infractions or misconduct. Without more context it's difficult to give a precise answer, but generally speaking, when someone with an existing amount of demerit points on their record accumulates new demerit points, it does not clear their existing points. Instead, the new points would typically be added to their record, potentially leading to more severe consequences such as license suspension, fines, or other penalties. It's important to consult the specific rules of the jurisdiction or organization's demerit points system to understand how new points interact with existing ones.
