Abstract: The stability of the $ {L_2}$-projection onto some standard finite element spaces $ {V_h}$, considered as a map in $ {L_p}$ and $ W_p^1$, $ 1 \leqslant p \leqslant \infty $, is shown under weaker regularity requirements than quasi-uniformity of the triangulations underlying the definitions of the $ {V_h}$.
