Bike locked to mine: am I allowed to cut through the lock on my own?
<p>Bob locked his bike. Two hours after he found another bike locked to his. Is he allowed to cut through the lock that doesn't belong to him on his own?</p>

<hr>

<p>I am mostly interested in the following locations:</p>

<ul>
<li>California, United States</li>
<li>Massachusetts, United States</li>
<li>Paris, France</li>
<li>Seoul, South Korea</li>
</ul>

<p>This is a fun one. I don't have any particular domain knowledge about this question. So this one is just a guess.</p>

<p>My answer is strictly from a practical standpoint. If I were faced with this situation in real life, what would I do? (Technical point: I feel the vagueness of the language, "Is he allowed to" allows me to answer this way.)</p>

<h3> My assumptions: </h3>

<p>My assumptions are that:</p>

<ol>
<li>The cost of consulting an attorney on the matter or filing a law suit would likely exceed the combined total cost of the bike and the lock.</li>
<li>Usually, the law follows what "feels right" and what makes common sense to the average person. Usually. Not always. But usually. <em>(Legal principles: "Equity follows the law." and "Equity does not aid a party at fault." <a href="http://legal-dictionary.thefreedictionary.com/%22Equity+follows+the+law.%22" rel="noreferrer">See this reference.</a>)</em></li>
</ol>

<h3>What I would do:</h3>

<p>So, I would do the following... (if I were in the U.S.)</p>

<p>I would simply cut the bike lock and repossess my bike (unilaterally) if and only if all the following conditions were true in the situation:</p>

<ol>
<li>I could confirm without any doubt that the bike in question is actually my bike and not just another one that looks just like it.</li>
<li>I could not find anyone around who looks like they might be the owner of the lock or the other bike. If I could find the owner of either the lock or the bike it is highly likely there was some mistake and the situation could be resolved directly with them.</li>
<li>There are no law officers nearby. If so, I would engage them in helping me rectify the matter. If they said it was a "civil matter" and refused to get involved, I would proceed to the next item on this list.</li>
<li>I had the tools handy and available to cut or break the lock.</li>
</ol>

<p>If any of the above conditions were false, I would flag down the nearest law officer or call one to the scene to help resolve the issue. Any other approach would seem impractical to me on the basis of my above assumption numbered 1.</p>

<p>If I were anywhere outside the U.S., I would involve the local authorities without considering the unilateral repossession option.</p>

<p>Yes, of course he can; he would probably need tools like bolt cutters or a hack saw unless he were very strong or the lock was very weak.</p>

<p>Perhaps you meant to ask if Bob is committing a crime or a tort by doing so?</p>

<p>For common law jurisdictions:</p>

<p>Yes, of course he is; the tort is known as Wilful Damage and the crime usually has a similar name.</p>

<p>The person who put the chain on is committing the tort of Conversion but probably falls short of the crime of Theft as there is no intention to <em>permanently</em> deprive Bob of his bike.</p>

<p>Bob's legal options are:</p>

<ol>
<li>Wait for or seek out the owner of the chain and ask them to remove it,</li>
<li>remove the lock without damaging it and reinstate the protection to the other bike, a locksmith may be needed; he could then sue to recover his costs,</li>
<li>Sue for a court order for the return of his bike, </li>
<li>involve the police who <em>probably</em> have the legal authority to damage the lock in removing it</li>
</ol>

<p>Just because someone has wronged you does not give you the right to wrong them.</p>

<p>For non- common law (France, Korea) I have no idea.</p>
