We discuss the limitations and rights which may affect the researcher’s access to and use of digital, court and administrative tribunal based information. We suggest that there is a need for a European-wide investigation of the legal framework which affects the researcher who might wish to utilise this form of information. A European-wide context is required because much of the relevant law is European rather than national, but much of the constraints are cultural. It is our thesis that research improves understanding and then improves practice as that understanding becomes part of public debate. If it is difficult to undertake research, then public debate about the court system – its effectiveness, its biases, its strengths – becomes constrained. Access to court records is currently determined on a discretionary basis or on the basis of interpretation of rules of the court where these are challenged in legal proceedings. Anecdotal evidence would suggest that there are significant variations in the extent to which court documents such as pleadings, transcripts, affidavits etc are made generally accessible under court rules or as a result of litigation in different jurisdictions or, indeed, in different courts in the same jurisdiction. Such a lack of clarity can only encourage a chilling of what might otherwise be valuable research. Courts are not, of course, democratic bodies. However, they are part of a democratic system and should, we suggest – both for the public benefit and for their proper operation – be accessible and criticisable by the independent researcher. The extent to which the independent researcher is enabled access is the subject of this article. The rights of access for researchers and the public have been examined in other common law countries but not, to date, in the UK or Europe.

The use of hot-melt extrusion (HME) within the pharmaceutical industry is steadily increasing, due to its proven ability to efficiently manufacture novel products. The process has been utilized readily in the plastics industry for over a century and has been used to manufacture medical devices for several decades. The development of novel drugs with poor solubility and bioavailability brought the application of HME into the realm of drug-delivery systems. This has specifically been shown in the development of drug-delivery systems of both solid dosage forms and transdermal patches. HME involves the application of heat, pressure and agitation through an extrusion channel to mix materials together, and subsequently forcing them out through a die. Twin-screw extruders are most popular in solid dosage form development as it imparts both dispersive and distributive mixing. It blends materials while also imparting high shear to break-up particles and disperse them. HME extrusion has been shown to molecularly disperse poorly soluble drugs in a polymer carrier, increasing dissolution rates and bioavailability. The most common difficulty encountered in producing such dispersions is stabilization of amorphous drugs, which prevents them from recrystallization during storage. Pharmaceutical industrial suppliers, of both materials and equipment, have increased their development of equipment and chemicals for specific use with HME. Clearly, HME has been identified as an important and significant process to further enhance drug solubility and solid-dispersion production. © 2012 Future Science Ltd.
