Because Gravity Falls "was founded by a mayor [Quentin Trembley] who was legally insane," it has many laws which are just as insane. After suffering a concussion and falling into a ditch, discovering Gravity Falls, Trembley wrote the town charter. Despite over 150 years having gone by since Gravity Falls was initially founded, and at least three other mayors having been in office, many of the odd laws remain unchanged.
Gravity Falls' unconventional laws include the following:
- Gravity Falls' mayoral elections are based on two events: the Wednesday Stump Speech, held on an actual stump, and the Friday Debate wherein townsfolk throw birdseed at the candidate they like most. At the end, they release a freedom eagle who will fly to the candidate covered in more seed and bestow a birdly kiss upon him, anointing him mayor. The Town Charter defines a worthy candidate as "anyone who can cast a shadow, count to ten and throw their hat into the provided ring." The office appears to be for life.
- As of 1922, beavers have the right to vote.
- Gravity Falls is the first and only city to officially outlaw "Moon People."
- The right to marry a woodpecker.
- Anyone in possession of the physical, legal document to a property gains ownership of that property (Finders Keepers Law).
- Instead of juvy, children are sent to adult prison.
- Town residents and visitors are forbidden from speaking of Weirdmageddon, and face tasering by law enforcement should they do so (The Never Mind All That Act).
- In 1920, a "Maple Syrup Prohibition" was enacted, leading townsfolk to gather in Pancake Speakeasies. This prohibition is not currently in force, since the use of maple syrup is now extended.
- "Irrational Treasure" - right to marry a woodpecker
- "Dreamscaperers" - Finders Keepers Law
