To what extent can a country enforce its laws in foreign countries?
<p>Let's say a hypothetical country Z makes a law that says:<br />
&quot;If anyone operates a website accesible within the borders of or accessible to the residents or citizens of country Z will have to pay $1 Billion&quot;<br />
May this law be refused to be enforced?I mean can another country A refuse this legislation on it's citizens or pass a law defending citizens against this without war or breaking treaties.</p>

<p>This is an interesting hypothetical. In this scenario, Country Z does not have jurisdiction to enforce such a law on foreign nationals, unless Country Z has an extradition treaty with Country A. Generally, however, these types of laws would never be enforced as they are egregious abuses of government, and could possibly be elevated to the International Court of Justice if Country Z actually charges any individuals with such a crime.</p>
<p>In these instances, however, war is a very unlikely scenario, since this would often be expensive and any escalation would most likely be small skirmishes that would lead to an eventual ceasefire, with the encouragement of the international community, without the involvement of UN Peacekeeping troops.</p>

<p>Countries are <a href="https://en.m.wikipedia.org/wiki/Sovereign_state" rel="nofollow noreferrer">sovereign states</a> which means that, ultimately, they do not have to abide any &quot;international law&quot;. Where they do, what they abide are agreements between countries — treaties. They do it merely for practial/political reasons, not because the world could somehow jail them. The measures against a defiant country that other countries could impose are basically asset seizures (where assets of that country can be found outside it) and other sanctions. In extreme situations the country may be invaded/fought against.</p>
<p>Now, if country Z makes a law like in your question, other countries will likely laugh and just ignore. All that country Z could do to enforce that law is basically attempt to block the website using its national firewall, seize any assets of the website owners <em>in Z</em> and arrest them should they travel via Z or its allies. Provided that the website owners do not care of any of that, they have nothing to worry about.</p>

<p>There are already countries with similar laws. Badmouthing the <a href="https://en.wikipedia.org/wiki/Big_Brother_(Nineteen_Eighty-Four)" rel="nofollow noreferrer">leader</a> / country / religion could end you in jail, if not worse. Naturally, only if/when caught.</p>
<p>On a different country, the same thing could be perfectly legal. If the offender is in country Z, he may have a hard time (country A embassy may help, but it your hypothetical country it would still be tough). If he is in country A, country Z would have to request to country A an extradition of the individual. If what he did was legal on A, it would be refused. Even if countries A and Z have an extradition treaty, it would be probably be possible to appeal that, blocking the extradition until the courts on country A decide on the matter.</p>
<p>He who commits such offense should not visit country Z, as they can expect to be arrested. Similarly, for countries friendly to Z. If that person left country A (from which Z is not able to extradite him) and has even just a layover at country Y -which sees eye-to-eye with Z-, they could be arrested there and extradited to Z. It requires effort from Z to coordinate the operation, but it happens, has been done in the recent past and you can find it on the news. If this was a cinema script, however, you will probably find a special commando kidnapping that person for his crime of publishing a website and taki9ng that to country Z.</p>
<p>Finally, if the ruler of country Z was really insane, he could indeed threat to drop a nuclear bomb on country A if they didn't provide that webmaster which didn't pay them (or pay the money themselves). I should note however, that he may not be the only crazy ruler with bombs...</p>

<p>I presume this ties into your question about selling Apps on a worldwide platform and your worries about liabilities, refunds, etc.</p>
<p>If the country Z is the United States, and they <em>really</em> want to come after you, you have a problem. They could order companies not to deal with you, and those companies must comply if they still want to <a href="https://en.wikipedia.org/wiki/Countering_America%27s_Adversaries_Through_Sanctions_Act" rel="nofollow noreferrer">do business</a> in the US. The US could also request your arrest and extradition and many countries would comply, because the US has leverage and also because of the US is seen as having a reasonable legal system.</p>
<p>If the country Z is in the European Union, or if it is China, you have less of a problem but still a problem. Their reach isn't as far as the US.</p>
<p>If the country Z is Zimbabwe, there is less reason to worry unless you live in Zimbabwe. They don't have all that much leverage.</p>
