Adverse possession
([update] There is a point but please read sequentially)

"In law, acquiescence occurs when a person knowingly stands by without raising any objection to the infringement of their rights, while someone else unknowingly and without malice aforethought makes a claim on their rights. Consequently, the person whose rights are infringed loses the ability to make a claim against the infringer, or succeed in an injunction suit due to the infringer's conduct. The term is most generally a kind of "permission" given by silence or passiveness.

Overview

The common law doctrine of estoppel by acquiescence is applied when one party gives legal notice to a second party of a fact or claim, and the second party fails to challenge or refute that claim within a reasonable time. The second party is said to have acquiesced to the claim, and is estopped from later challenging it, or making a counterclaim. The doctrine is similar to, and often applied with, estoppel by laches."

"Silence is acquiescence (aka. silent acquiescence and acquiescence by silence) is a related doctrine that can mean, and have the legal effect, that when confronted with a wrong or an act that can be considered a tortious act, where one’s silence may mean that one accepts or permits such acts without protest or claim thereby loses rights to a claim of any loss or damage.[2]"

"Malice aforethought is the "premeditation" or "predetermination" (with malice) that was required as an element of some crimes in some jurisdictions,[1] and a unique element for first-degree or aggravated murder in a few.[1]"

"Adverse possession is a process by which premises can change ownership. It is governed by statute[1] concerning the title to real property (land and the fixed structures built upon it). By adverse possession, title to another's real property can be acquired without compensation, by holding the property in a manner that conflicts with the true owner's rights for a specified period. For example, squatter's rights are a specific form of adverse possession.

•Dispossession not under force of arms. Dispossession by armed invasion does not establish a claim of adverse possession against the true owner."

[update] Discussion:

a) In general, know your own rights, and if infringed, OR someone aggresses against you, speak up, loudly, and make a public record.

b) In particular, the above is to show that Israel (=IL) illegally squats on mostly Palestinian land/property, and can *never* have legal title to that land/property (before WW2, the Zs had managed to purchase ~6% of pre-UNGA181 Palestine; that much is legally theirs). Thus, as illegal squatters AND as the mostly Palestinian ELO/Os expressed their rightful claims before the Zionists' aggressive invasion began in earnest, the entity IL can never claim legitimacy, since they do not and never can own the land they improperly dispossessed from the ELO/Os - unless those ELO/Os surrender = roll over, which is of course, the despicable Zs' long-term aim = the risible 'peace process.'

My advice to Palestinian refugees (i.e. all driven = dispossessed from pre-UNGA181 Palestine), their heirs and successors: Never surrender!
