We study a probabilistic one-dimensional majority-rule two-state cellular automaton and examine the stability of ordered magnetised states in systems of size L as the neighbourhood radius R varies. We find that a scaling $R \sim \ln L$ is sufficient for an ordered phase to be metastable, i.e., to survive for times much longer than the typical critical fluctuation. The lattice magnetisation obeys a scaling relation which agrees with results from mean-field analysis.
