How to mention an amendment to the U.S. Constitution in text in APA style In the dissertation, several amendments are mentioned in a general way. Do you spell out the amendment numbers or not or does it matter? 


Justice Douglas addressed the Eighth Amendment and the Fourteenth Amendment ...
Justice Douglas addressed the 8th Amendment and the 14th Amendment ...


The university handbook is silent on the matter, so APA style prevails. I looked in the APA 6th edition, which shows examples for in-text citations and for reference entries. But could not find any examples of a general nature. 

I also do not have access to the Legal Bluebook.
Received an answer at the APA style blog: 

Regular number formatting applies when an amendment is mentioned as part of a sentence: spell out for the first through ninth amendments and use numerals thereafter
(e.g., “the fourth amendment,” “the 12th amendment”).
