Justice Ketanji Brown Jackson, meanwhile, joined the majority opinion offered by Chief Justice John Roberts, but wrote her own concurring opinion.
The law bars people from altering, destroying, mutilating, or concealing “a record, document, or other object, or attempts to do so, with the intent to impair the object’s integrity or availability for use in an official proceeding” and “otherwise obstruct[ing], influenc[ing], or imped[ing] any official proceeding or attempts to do so.”
The ruling focuses on the “otherwise” word, finding that, based on historical context, it only applies to the list of criminal activities listed before it.
Under the government’s broader interpretation, even peaceful protesters could be charged and face a sentence of up to 20 years in prison, Solicitor General Elizabeth Prelogar has acknowledged. That interpretation would transform “this evidence-focused statute” into a “one-size-fits-all solution to obstruction of justice,” Justice Roberts said.
To prove a violation of the law, according to the majority, “the Government must establish that the defendant impaired the availability or integrity for use in an official proceeding of records, documents, objects, or other things used in an official proceeding, or attempted to do so.”
“The upshot is that, when interpreting the scope of a particular statute or rule, our assessment of the words that the drafters used informs our understanding of what the rule was designed to do. Discerning the rule’s purpose is critical when a court is called upon to interpret the provision,” she wrote.
The majority also consisted of Justices Clarence Thomas, Samuel Alito, Neil Gorsuch and Brett Kavanaugh.
“Because it simply cannot believe that Congress meant what it said,” she said, describing the law in question as “a very broad provision.”
Justice Barrett was joined by Justices Sonia Sotomayor and Elena Kagan.
