Abstract
It is shown that the self-interaction term λ(AμAμ)2 added to the free Lagrangian for Maxwell's equations leads to acausal propagation. Furthermore, it is found that apart from the term λAμAμ which leads back to the Proca equation, all self-interaction terms leading to causal propagation must be nonpolynomial.
