Catchword
The standard burden of proof in opposition cases is generally expressed as proof on the balance of probabilities, absolute certainty is not required but a degree of probability which in human experience verges on certainty. If the evidence is such that the Division or the Board can conclude "we think it more probable than not", the burden is discharged. The burden of proof may shift constantly as a function of the weight of the evidence (cf. point 2.10 of the Reasons for the Decision).

ORDER

For these reasons, it is decided that:

1. The decision under appeal is set aside.

2. The case is remitted to the Opposition Division for further prosecution.
