It will be proved that the Shoenfield cupping conjecture holds in R/M, the quotient of the recursively enumerable degrees modulo the cappable r.e. degrees. Namely, for any [a], [b] $\in$ R/M such that [0] $\prec$ [b] $\prec$ [a] there exists [c] $\in$ R/M such that [c] $\prec$ [a] and [a] = [b] $\vee$ [c].
