Anyone Been To Court And Successfully Disputed Ticket?

I just wanted to know if anyone's been to court and successfully disputed their ticket.

If so,

1. What were you charged with? Details about the incident, etc.

2. Your experience before going to court, i.e. early resolution meeting with prosecutor, filing a notice of constitutional question, asking for adjournments, requesting for disclosure, how long it took to get to trial, etc.

3. What happened once you were in court? i.e. dismissed or withdrawn, police officer didn't show up, arguments/evidence you used, etc.

Here are my cases:

Driving Handheld Communications Device - lost trial and lost appeal (first time ever in court, good learning experience).

Speeding - lost trial but WIN on appeal: http://www.ontariohighwaytrafficact.com/topic7286.html
