In the first case I have seen addressing this issue, reasons for judgement were released today by the BC Supreme Court, Vancouver Registry, striking out language in correspondence between lawyers as an abuse of process.
In today’s case (Walker v. Doe) the Plaintiff objected via letter sent to Defence counsel to the admissibility of Defense expert reports, and as part of the “boilerplate” objections Plaintiff’s counsel noted that “we shall seek sanctions personally against [expert’s name], including but not limited to special costs“.
In finding that the Rules of Court allow a Judge to strike out language in such a letter Mr. Justice Butler reasoned as follows:
 Letters sent by counsel to provide notice of objection to the admissibility of an expert report are required to be served pursuant to R. 11-6(10). The notice must set out “any objection to the admissibility of the expert’s evidence that the party receiving the report … intends to raise at trial.” The notice required by the Rule is a document mandated by the Rules in which a party must set out their position for trial.
 Rule 9-5(1) is not limited to pleadings but also applies to petitions and “other documents”. Document is defined in R. 1-1(1) in broad terms. There is no doubt the notice required under R. 11-6(10) is a document pursuant to that definition. However, the word must be interpreted ejusdem generis in the context of the phrase, “pleading, petition or other document”. Applying that aid to interpretation, I conclude that “other document” refers to documents which are required by the Rules to formally set out a party’s position, claim or defence. The notice under R. 11-6 (10) is such a document.
In finding the costs threat amounted to an abuse of process the Court provided the following reasons:
 In conclusion, expert witnesses play an important role in the litigation process. When an expert is properly qualified within an area of expertise and the expert’s opinion evidence, which is not otherwise excluded, meets the essential criteria of relevance and necessity in assisting the trier of fact, it can be admitted to assist the court: R. v. Mohan,  2 S.C.R. 9. The Rules establish a process which provides adequate notice of expert opinions and sets up a way to challenge admissibility. There is no need to introduce into the process, by way of boilerplate language in notices under R. 11-6(10), threats of claims against experts for special costs. As I have already noted, it is entirely unnecessary. Further, it has the potential to frustrate the litigation process because it may discourage the participation of expert witnesses. In addition, and contrary to the intent of the new Rules, it would seem to place the expert in an adversarial position.
