What legally would happen if you murdered your conjoined twin vs your twin? Has there been a case where a conjoined twin murdered their other half and survived? What was the out come? One of the twins have control of the body and the other one is intelligent but can only communicate by blinking or lip smacking. Lets say they go to Mexico and only half came back. What could the twin expect from legal repercussions or exemptions?
Murder is Murder Adding all the elements of murder are proven beyond reasonable doubt then the person gets convicted. The fact that they were a sibling would be considered in sentencing as it always is.
If an adult had physically restrained the miscreant brat, they could be sued for / charged with battery (which does not mean "beating up", per Cal Penal 242, it is the "willful and unlawful use of force or violence upon the person of another". In either case, there is a defense that can be mounted, the "defense of others" defense, to the effect that the person had a reasonable belief that it was necessary to prevent physical harm to others. Which means, the jury would imagine themselves in that situation and guess how likely it is that someone might get hurt. Lofting 5 lb chess pieces at a 2 year old could poke out an eye, especially since they haven't learned to duck at that age – however, I question (as would an opposing attorney) the characterization "quite dangerous". At any rate, it would depend on the level of danger posed. There is also a "proportionality" requirement for the defense of others defense: "The defendant used no more force than was reasonably necessary to defend against that danger" (CalCrim instruction 3470). The battery might not have been necessary, since simply getting between the criminal and his victims could have been sufficient. As to whether there would actually be a lawsuit, that depends in part on the mind-set of the parents. Assuming that the level of force did not rise above simple bodily contact, it is unlikely that a jury would vote to convict / find liable, but certainly not impossible. If under those circumstances the results would not be in serious doubt, then it is unlikely that the person would be prosecuted (the prosecutor wouldn't bother with such a case). We may also assume that a decent attorney would persuade the offended parent-client that it is not a good use of their money to pursue he matter. Still, the risk is not negligible, since you don't know whether you'll have bad luck with the jury, or whether the child suffers from eggshell skull syndrome and then you would be is serious trouble. I don't think the fears are unrealistic, though they may be improbable, and they could be definitive for people who live in fear.
There is no prospect for equitable relief in such an outcome. The Texas state government enjoys sovereign immunity, except as specified under the Tort Claims Act. Under that law, immunity is waived only in the case of damage caused by negligence of a state employee, and is limited primarily to vehicle accidents and physical injuries. So the state cannot be sued for passing a law found to be unconstitutional. An individual would not enjoy such immunity, but given the law, there is no identifiable defendant to seek relief from (everybody is a potential defendant). An former abortion provider who now declines to perform an abortion can't be sued, because doctors in general have no obligation to perform particular medical procedures (most doctors in Texas won't perform an abortion, even before SB8), and the course will not render a judgment against a doctor on the grounds that they obeyed an existing law but should have known that it would be found unconstitutional.
Murder is one of the few cases where the intention and not just the act is relevant. The act – killing a person – is the same for Mord and Totschlag, whereas fahrlässige Tötung covers acts that have caused the death of a person. The language of the Stgb labels the perpetrator who killed someone as a murderer or manslaughterer depending on their intention. That a person and not an act is punished is often criticized, but it has no practical consequence. Clearly, the intention isn't that the second one is free. Courts are able to interpret the law reasonably. However, the distinction between two kinds of killings seems to have no basis in reality and robs courts from flexibility to find a just sentence. There are occasional attempts at reform, but none will be successful while CDU/CSU is part of the government.
The Fifth Amendment, in pertinent part, reads: "nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb;" which suggests that Crime B is still fair game under double jeopardy. However, if B is a lesser included offense under Blockburger, i.e. A is Aggravated Robbery and B is Robbery, then a prosecution could be barred by Double Jeopardy. Barring that, and jurisdiction specific law, the State isn't barred by the Double Jeopardy clause of the 5th (and 14th) amendment. That does not foreclose Person C from finding an ethical, equitable, statutory remedy or controlling case enforcing a plea bargain. As far as I can tell, commutation is the equivalent of a conviction while a pardon is equivalent to an acquittal. I also imagine if the prosecution isn't barred and tried C for B, the Executive may just pardon/commute C again. Edit to add: Under Santobello, it would appear C may have an additional remedy enforcing a plea bargain. Santobello didn't involve a case dismissed in a plea bargain, nor commutation or pardon. A court might find that commutation or pardon are essentially a breach of the agreement.
No, if, as you say we put aside the human rights questions surrounding the death penalty itself and assuming that the prisoners had been legitimately charged, convicted and had exhausted their appeals process. Once a person has been convicted, sentenced to death and has exhausted their appeals then the timing of the execution passes from the judicial branch to the executive branch of government. This is why governments can implement and remove moratoriums on executions at their discretion. Doubtless there are administrative rules and logistical issues involved in the actual timing of the execution but if these have all been correctly dealt with then they are essentially held at the pleasure of the person in the government charged with the decision. Was it legal? Probably. Was it ethical? ...
A problem with the question is that it uses the loaded term "victim". If you change the question to "Are there actions that you can perform involving another person, which are crimes even if the other person consents to participating in the action", then there are very many. Selling alcohol to a minor; selling heroin to anyone; selling sex in most US jurisdictions; selling firearms to a convicted felon. Also, for a physician to assist a person in suicide, in most states. Formerly in the US, various forms of sexual intercourse were acts that consent did not make legal. Whether or not the person is a "victim" in these cases is open to debate. In the case of physician-assisted suicide in Washington, the doctor is allowed to prescribe (oral) drugs that the person ingests: only a doctor is permitted to do this, both under the DWD Act and as a consequence that only a doctor can prescribe the drugs. There seems to be a belief that it is a crime to assist a person in committing suicide, which is probably correct if the assistance is shooting the person in the head, or in general directly causing the death (thus, "I give you permission to shoot me in the head" doesn't cut it). But from what I can tell, it is not generally against the law in Washington to help a person who commits suicide (e.g. supplying the means of self-dispatching). In some countries, suicide and helping with suicide is illegal, e.g. in Kenya Penal Code 225 says Any person who (a) procures another to kill himself; or (b) counsels another to kill himself and thereby induces him to do so; or (c) aids another in killing himself, is guilty of a felony and is liable to imprisonment for life. No exception is created if the person consents to being aided to kill himself.
The law does not criminalize "having more than 1 legal spouse", it criminalizes specific behavior. The polygamy statute is here. It says Every one who (a) practises or enters into or in any manner agrees or consents to practise or enter into (i) any form of polygamy, or (ii) any kind of conjugal union with more than one person at the same time, whether or not it is by law recognized as a binding form of marriage, or (b) celebrates, assists or is a party to a rite, ceremony, contract or consent that purports to sanction a relationship mentioned in subparagraph (a)(i) or (ii), is guilty of an indictable offence and liable to imprisonment for a term not exceeding five years. That is, if you behave like you're married to multiple women, you've committed a crime.
