The first instance concerns LaViolette's attempt to post a paper which announced confirmation of a prediction he had published in 1985, which predicted the phenomenon now known as the Pioneer Effect, this prediction being made many years prior to the effect's discovery in the early 1990's.  Dr. LaViolette's paper, entitled "The Pioneer maser signal anomaly:  Possible confirmation of spontaneous photon blueshifting", is available for examination and free download.  

This paper was a legitimate paper for posting to ArXiv.org for the following reasons:

1)	Paper was submitted to a journal: The paper had been submitted for journal publication, and the archive administrators had been informed of this.  The archive states that one of its purposes is to give authors a chance to communicate their findings prior to formal acceptance for journal publication.
2)	Good publication track record: The submitted paper discussed a phenomenon that was predicted by an established physics theory known as subquantum kinetics.  Subquantum kinetics had previously been published in a refereed journal of high repute (International Journal of General Systems).  In fact, this journal placed such high esteem in this theory that it devoted an entire issue to its exposition, printing all three foundation papers in one issue entitled "Special Issue on Systems Thinking in Physics."  This was followed by publications in other journals such as the Astrophysical Journal and Physics Essays, which explored the astrophysical implications of the theory.  Also subquantum kinetics has had ten of its predictions now verified; see Predict2.html.
3)	Topic Appropriate for the Archive: The topic of the submitted paper was appropriate since the archive already had dozens of papers posted on the discovery of the Pioneer Effect, many of which attempted to offer various unconventional physics theories as a way to explain it.  None of these posted theories had been proposed a priori.  All were devised a posteori in hindsight.  Many of these papers had not been submitted for publication but were posted because this section of the archive had evolved into a forum for discussing this particular phenomenon.  None of these posted papers mentioned the a priori prediction LaViolette had published in 1985, most being unaware of it.  Hence this discussion forum would have stood to benefit from the knowledge that an a priori prediction of the Pioneer Effect had been made.
4)	The Reported Finding could Make an Important Contribution to Fundamental Physics:     The submitted paper discussed a quantitative prediction which LaViolette made as early as March 1980 which predicted that photons should gradually blueshift and which specified the rate at which this blueshifting should take place.   Also that same year, he had noted that this effect would be large enough to observe in maser signals transponded between spacecraft.  Furthermore the blueshifting rate observed in the Pioneer data many years later and discussed in the posted papers matched the predicted rate to within two standard deviations, essentially confirming the theory.
	Theoretical confirmation is a serious affair in physics and is recognized as a means by which a novel theory is judged to be superior over existing theories.  To thwart the communication of such an important verification is to essentially thwart the progress of science.  Especially in this case this theory concerns a fundamental assumption that has wide import for both physics and astronomy, namely the First Law of Thermodynamics.
5)	Paper had well qualified endorsers, including one Nobel Laureate:  Three physicists including one Nobel Laureate, Hans Bethe, have attempted to sponsor LaViolette's paper, attesting that it is worthy of being posted.  Dr. Bethe is one of the codevelopers of the big bang theory and originator of the idea that stars are powered by fusion energy.  But in all cases the archive has ignored the attempts of these scientists to sponsor LaViolette's paper.  One of the scientists who came forth to sponsor LaViolette's paper had earlier posted papers to the archive on the Pioneer Effect.  Hence he was also well qualified to serve as a sponsor, being particularly knowledgable on this subject.  The Cornell physics archive had posted endorsement instructions that scientists were to follow in order to become qualified to post their papers.  But even though he had satisfied these posted requirements many times over, his efforts to attain registration were nevertheless blocked.
6)	Topic is of heated interest: The paper submitted for posting is on a topic that is of interest to both the physics and astrophysics community, namely the Pioneer Effect.  Since standard physics theories have been unable to account for this blueshifting effect, it has generated considerable interest, and as a result many articles have been written about its discovery in the press.  Consequently, any theory that can give a reasonable explanation of the effect would be of great interest not only to the scientific community but to the general public as well.
7)	Discovery Team have not acknowledged prediction in their publications:  Paul LaViolette had made several attempts to contact the Jet Propulsion Laboratory (JPL) scientists who discoverered the Pioneer Effect to inform them about the subquantum kinetics a priori prediction, but those team members who announced this discovery and posted papers about it on the Cornell preprint archive have not cited his prediction.  It is imperative then that LaViolette be given the opportunity to communicate his theory's early prediction to this internet archive forum in order to rectify this past citation omission.
	The first time that LaViolette contacted scientists at JPL was in 1980.  At that time he told them that his theory predicted that a blueshifting effect should be observed in spacecraft maser signal transmissions and told them the amount of blueshifting that could be expected.  John Anderson, who spearheaded this work at JPL was part of the same group of researchers with whom LaViolette had spoken.  After that Anderson began to notice the effect in the Pioneer 10 data and finally in 1992 he decided to initiate a formal study of the data.
	LaViolette's second contact was directly with Anderson on September 25th, 1998, one week before he posted his seminal discovery paper on the physics archive and eleven days before publication of his paper in Physical Review Letters.  Anderson sounded interested in LaViolette's blueshifting prediction and had planned to work out whether the predicted amount could account for the anomaly they had observed in their data.  LaViolette also sent him a copy of his book Subquantum Kinetics (first edition) which detailed this prediction and noted that it had been published as early as 1985.  But neither did Anderson send LaViolette a copy of his forthcoming paper nor did he contact him.  Moreover, Anderson apparently forgot to mention this a priori prediction in his more lengthy paper which he published in 2002 in Physical Review D and posted on the physics archive on January 21st of that year.  Neither did he mention anything in another paper his group posted on the physics archive in 1999.

Consequently, not only has Paul LaViolette's Pioneer Effect prediction remained unrecognized in the journal literature, but his attempts to bring this prediction to the attention of the scientific community through archive posting have been met with a closed door.  Nevertheless, his paper has now been accepted for journal publication and is due to come out shortly.  It is disconcerting that the archive administrators would allow other physicists to post their papers prior to journal publication and at the same time block LaViolette's repeated attempts to post his paper.
