Under the penalty point system, if Julia accumulates 12 or more points within three years, she will be disqualified for a minimum period of six months unless she has been disqualified for a period of 56 days or more within the last three years, which she has not. The court typically does not impose a longer disqualification than the minimum period unless there are exceptional circumstances. Option A is incorrect as 56 days is too short and not applicable under the penalty point system. Option B, while common in practice, does not mention it as the minimum period. Option D is incorrect as Julia has not been disqualified for more than 56 days within the last three years. Option E is incorrect as it overstates the typical disqualification period for the given circumstances. 

Key Point: Understanding the disqualification periods under the penalty point system is essential for advising clients accurately on the potential outcomes of their driving offences and the cumulative impact of their driving record.
