What did the court decide in Sniadach v. Family Finance Corp. of Bay View?
Answered for: US
Where the taking of one's property is so obvious, it needs no extended argument to conclude that absent notice and a prior hearing (cf. Coe v. Armour Fertilizer Works, 237 U. S. 413, 423) this prejudgment garnishment procedure violates the fundamental principles of due process.
The Court held that garnishing wages before judgment, without notice and a hearing, violates due process.
This answer is true in US and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for US.
