What happens if bad lawyer advice causes irreparable harm? Let's reduce the question to Canadian lawyers in immigration practice. Bad advice can cause loss of residency, lifetime ban and more. What's your recourse?
If the lawyer was negligent, you can sue Note that negligence requires considerably more than just being wrong . Professional advice (including legal advice) requires assessment of risks and strategies and advising the client of these so they can make informed choices about their options. There is plenty of scope to make mistakes, however, a lawyer who does what a reasonable lawyer (not an expert lawyer) should do has not been negligent. You cannot sue for anything done or said by the lawyer in court - this is a public policy thing to stop disappointed litigants from suing their lawyer if they lose.
If the patent lawyer &quot;hears about&quot; such failed patents from clients, and then uses the client's work and modifies them into successful patent filings, that would seem to be a clear conflict of interest, just as a business lawyer cannot use info learned from a client to make his own business deals, unless the client grants an OK. But if the patent lawyer just hears through shoptalk, or through communication by, perhaps, patent examiners that the lawyer works with, I don't see any conflict of interest, although as the comment by Eugene Styer suggests, there is likely to be enough prior art to make the patent invalid.
If you innocently took the oven glove by mistake there is no possibility of criminal consequences. Now that you know it is not yours, you must return it as soon as possible. You may be liable for the losses caused by taking the glove, and that could extend as far as some fraction of the cost of a replacement glove if they have already replaced it. You cannot (legally) hold his glove hostage for the return of your desk. Deciding which glove is which is tricky. Given the cost of new oven gloves, I would go round with both and ask him which is his. Even if he takes the nicer one which isn't his, you are only down a few dollars. The messy hall should be a separate question (and risks being closed as asking for specific legal advice - I think you need your own paid-for lawyer for that).
The consequences for the US are perhaps better addressed at Politics; if you're really interested in those consequences, you can re-post this question there. For the police officer shooting a diplomat, the officer may be charged under state law, whatever is normal for an incident of this type; it doesn't matter whether the person is a US citizen or a diplomat or any other kind of alien, regardless of immigration status or lack thereof. If the person is a diplomat, however, the officer is also liable to be prosecuted under federal law, namely 18 USC 1116, which makes it a crime to kill, among others, a "foreign official"; the definition of that term includes any person of a foreign nationality who is duly notified to the United States as an officer or employee of a foreign government or international organization, and who is in the United States on official business, and any member of his family whose presence in the United States is in connection with the presence of such officer or employee. The characterization of the response "just been revoked" as "clearly legal" is inaccurate; a police officer has no power to revoke diplomatic immunity. In fact, only the diplomat's own country can waive this immunity. The United States cannot do so; it can only expel the diplomat.
Law SE is not for direct legal advice. You're in the middle of a contract dispute that has turned acrimonious and need to find legal help. Google for free or low cost legal aid in your area. If this "point person" has mentioned a lawyer or made legal threats, you do need legal help.
Your kid is not in trouble; he's a minor. You're in trouble. A criminal case for the charges a prosecutor would bring, i.e. destruction of property (the data) or for a relevant cyber or computer crime (malware, etc.), and/or a civil case for damages due to the destruction of the data would both hinge on one point: the concept of intent. See intent - Wex Legal Information Institute and Civil Law vs. Criminal Law: The Differences | Rasmussen College. Did you knowingly intend to cause damage or data loss with the structure of the name? It's pretty clear you did. The structure of a name that can invoke an SQL command is not in any sense a standard name in spelling or format or punctuation. So how would you convince the jury or judge that you had no intent when you named your kid? The possible poor design of a data system that didn't sanitize inputs is no defense. Saying the door was unlocked so I assume the homeowners didn't care if I trashed their house will get you laughed into jail or on the hook for a stiff civil judgement.
Legal Services Society is a non-profit organization created by the BC Legislative Assembly through this act, created in order to serve the legal needs of certain classes of society, defined vaguely with reference to "a reasonable person of modest means". Accordingly, they have rules regarding who they can and cannot serve. and they are constrained financially. With vast demands on their resources and little by way of resources, prudent triage is called for. That is, when you show up, you shouldn't expect to talk to a senior attorney (or an attorney). From what I can determine, you cannot expect to get your problem solved right away. It is also not clear that your problem is within the scope of what they do (criminal, incarceration, serious family matters, immigration). "Giving legal advice" is something that only a few people are legally allowed to do – lawyers, who have you as their client. If the person were an attorney, they still couldn't give you legal advice until the appropriate relationship is created (and they have the relevant facts). The person you met with may be a paralegal or a law student. Under the law (sect. 8 of the act), you cannot sue them for damages because of their actions, except if carried out in bad faith. The waiver might be a bit redundant, but it is a wise idea to tell people that you can't sue them. If you want to know what you can expect from the lawyer, this publication will be helpful, though it is generic and not specific as to your particular issue.
There is a legal concept of de minimis: the idea that some offenses, civil or criminal, are too small to be worth prosecuting. For example, a photograph of a city scene that incidentally captured part of a copyrighted billboard in one corner of the image infringes the copyright on that billboard. But if the copyright holder were to sue, it's virtually certain the suit would be thrown out due to the minimal nature of the infringement. Technically speaking, yes, what you describe is a crime. But any prosecutor who tried to bring charges to that effect is likely to be chewed out by the judge for wasting everyone's time. (Incidentally, assuming the reporter and property owner are US citizens, the crime is failure to cross at a designated crossing point (19 USC 1459, a customs offense) rather than improper entry (8 USC 1325, an immigration offense).)
