See paragraphs 37 et.seq. on rules 
The associated canon of construction—expressio unius est ¶38
exclusio alterius (expressio unius)—holds that “to express or include 
one thing implies the exclusion of the other, or of the alternative.” 
Expressio unius est exclusio alterius, BLACK’S LAW DICTIONARY (11th 
ed. 2019); see also Pulham v. Kirsling, 2019 UT 18, ¶ 30 n.9, 443 P.3d 
1217 (citing the above definition). And while canons of 
construction “are not formulaic, dispositive indicators of statutory 
meaning,” they serve as “tools that guide our construction of 
statutes in accordance with common, ordinary usage and 
understanding of language—in this instance, the expectation that 
legislators typically use language advisedly and tend not to speak 
in superfluous terms.” Olsen, 2011 UT 10, ¶ 19.
