I am seeing pattern where laws that used to serve some purposes is now serving very different purposes. I wonder if there is a name for these patterns.
Beyond reasonable doubt are there to protect jury. Juries at that time fear that they will go to hell if they convict an innocent man. So the rule is made that the jury must conclude that the defendant is guilty beyond reasonable doubt.
Of course, the purpose and the meaning is no longer there. The purpose of beyond reasonable doubt cases is now a way to protect defendants.
That's because, of course, values have changed.
US have become secular countries. Yada yada.
Statutory rapes laws also evolved.
It says that statutory rapes laws are there to protect virginity of young girls.
That would make a lot of sense.
Virginity was very important at that time.
Virginity of boys are "worthless" and hence not worth protecting. So a hot beautiful young teacher having sex with young boy would be "nice".
However, as times go buy, we have men and women treated equally.
Also marital age have gone up and virginity is not important anymore.
So now, statutory rapes would actually protect a 15 years old boy that rape an 21 years old girl. That 21 years old girl will have strong incentive not to report the rape due to statutory rapes law.
When an adult is raped by a juvenile, the offense of statutory rape imposes criminal liability on the adult for the same intercourse by which the adult is a victim of rape. In this way, the offense of statutory rape criminalizes being raped; it criminalizes being the victim of rape. It criminalizes the failure to prevent or resist being raped by a juvenile. And neither defenses specific to statutory rape nor defenses of general application satisfactorily preclude liability.
Another sample I can think off is adultery laws. Before paternity tests, adultery means paternity frauds. Men with power and wealth will end up inheriting his wealth to someone else' child if his wife commit adultery.
We can just use paternity tests to know who the father of the child is. So adultery laws become meaningless. In most states it's legal. Being legal, getting married no longer protect men from paternity fraud. If anything, getting married expose men to more liability of paternity fraud.
Are these "evolving idea", or phenomena, where a rule makes a lot of sense a long time ago, but somehow have been very different now have a name? So the laws were there for a reasonable purpose. And now the law is there for totally different purpose.
What are these called?
