Term for obligor that breaches his duty
<p>I'm looking for an appropriate term for an obligor that breaches a duty. It should apply to tort and contractual duties and to substantial as well as procedural law.</p>
<p>I would also be interested in a corresponding passive term (for &quot;obligor,&quot; it is &quot;obligee&quot;).</p>

<p><strong>Tortfeasor</strong></p>
<blockquote>
<p>A wrongdoer; an individual who commits a wrongful act that injures
another and for which the law provides a legal right to seek relief; a
defendant in a civil tort action.</p>
