The Ann Arbor City Council allows an unlimited number of citizens each to speak for 3 minutes at a public hearing. While no individual can speak for enough time to talk down council from making a decision, a collective effort with over 90 speakers was enough to derail any substantive decision-making at the April 15, 2013 council meeting.

In response, City Council is considering (as of June 2013) amending council rules to reduce speaking time to 2 minutes.

In the news 

Ann Arbor's City Charter does not allow for a citizen's filibuster (as far as I know). Nevertheless, at Monday's city council meeting we witnessed something like a collective citizen's filibuster: 45 people spoke at the public hearing for the proposed changes to the DDA and 51 people spoke at the public hearing for the 413 E Huron site plan approval. In the end, the city council postponed votes on both these controversial issues and ended the meeting at 3 am.

The Ann Arbor city council meeting that started on Monday evening, April 15, 2013 did not end until after 3 a.m. the following day. This was due in part to a stream of about 100 citizens who took the podium for general public commentary and two significant public hearings. The three-minute allocation of time per speaker translated into about five hours of public speaking time.
