We have had more encounters in the past few years (most friendly, some not) regarding our right to hunt our own property (or family members) if someone else got there first.
[font=Verdana, Helvetica, Arial, sans-serif]As a natural resource manager who oversees the submerged lands program in a coastal State, I am well versed on this subject, and not just as it applies to Alabama. Find a copy of a book called the "Putting the Public Trust Doctrine to Work" (Slade, et al, 1997), its a good read for any one who owns coastal waterfront property and those who use coastal waters adjacent to those properties.[/font]
From dealing with waterfront (riparian) property owners for the last 10 years, I can tell you they have a lot of misconception about what they own, what their rights are and what the rights of the public are. And some of them are downright arrogant and will do things that are flat out illegal in attempt to restrict the public's rights below mean high tide or even to prevent a neighbor from expressing their riparian rights. Its simply mind boggling at times. Not saying it's whats happening in your case, just making a point that there is a lot of misunderstanding and bad blood out there.
[font=Verdana, Helvetica, Arial, sans-serif]Right off the bat, lets establish that if the submerged lands & waters below mean high tide, it is not "your own property". It is public property.[/font]
[font=Verdana, Helvetica, Arial, sans-serif]In the vast majority of states, along tidal waters, the property line between public submerged lands and adjacent privately owned uplands is the mean high tide line. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]The adjacent upland owner (your brother-in-law in his case) has certain riparian rights on the adjacent submerged lands below mean high tide. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]Those riparian rights vary by state but usually include the right to build docks, wharfs, piers and similar structures, subject to the lines and limitations imposed by the state and federal governments. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]However, the public also has the right to fish, bath, [/font]hunt, traverse and/or [font=Verdana, Helvetica, Arial, sans-serif]navigate on or above those submerged lands below mean high tide. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]These public rights are just as "strong" as the adjacent upland owners' riparian rights. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]Neither may significantly interfere with the others expression of their rights, with the exception in (almost) all cases that no one may cause a hazard or impairment to navigation, navigational servitude takes precedent.[/font]
[font=Verdana, Helvetica, Arial, sans-serif]
[/font]
[font=Verdana, Helvetica, Arial, sans-serif]So, what this means is you do not have the "right" to ask someone to leave if they are floating or standing below mean high tide, were setup first and are otherwise not trespassing or violating safety zone or other state regulation. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]What may seem like a violation of etiquette to you is simply a member of the public trying to express their right to hunt, fish, boat, etc., where they have a right to do so. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]Look at it this way: I go out the day before, scout, find a bunch of ducks along the marsh in front of your property. I get to the ramp early, get out to the spot well before shooting time, setup my boat blind, put out my decoys and settle in. I did everything right and legal. Then you come along and ask me to leave???? From my perspective, it is you who are showing a lack of etiquette and consideration. [/font]
[font=Verdana, Helvetica, Arial, sans-serif]I will say this: The public most likely also has no right to build a permanent blind (structure) in front of your upland property within your riparian area, as defined by your state. They can anchor a boat and hunt, fish, bath, etc, as they see fit. But they cannot build a permanent structure. If this happens you have the right to ask the Corps of Engineers & State to investigate and will most likely be told you have the right to remove it. But make sure to go through proper procedures for your state,[/font]
