  It has recently been proposed, on the basis of eclipse-timing data, that the
eclipsing polar cataclysmic variable HU Aquarii is host to at least two giant
planets. However, that result has been called into question based upon the
dynamical stability of the proposed planets. In this work, we present a
detailed re-analysis of all eclipse timing data available for the HU Aquarii
system, making use of standard techniques used to fit orbits to radial-velocity
data. We find that the eclipse timings can be used to obtain a two-planet
solution that does not require the presence of additional bodies within the
system. We then perform a highly detailed dynamical analysis of the proposed
planetary system. We show that the improved orbital parameters we have derived
correspond to planets that are dynamically unstable on unfeasibly short
timescales (of order 10^4 years or less). Given these results, we discuss
briefly how the observed signal might in fact be the result of the intrinsic
properties of the eclipsing polar, rather than being evidence of dynamically
improbable planets. Taken in concert, our results highlight the need for
caution in interpreting such timing variations as being planetary in nature.
