Once a plan has been provisionally approved by the appropriate planning and building committee, it must be submitted for public review (for at least 60 days). During this time, affected and interested parties may object to the plan. At the end of the deposition period, the objections are reviewed, hearings are held, and a decision is made whether to accept, partially accept or reject the objections. Acceptance of an objection may require significant changes in the plan (or the drawing of a totally new plan), in which case it must be deposited for public review again, or the plan may be completely rejected. In most cases, a sub-committee hears the objections, but Israeli law allows an investigator to be appointed instead, where a large number of objections or exceptionally complicated objections are filed.
